You can set his program to either VT100 or VT102, but the operational behavior is essentially identical. The two settings differ only in how the emulation responds to a terminal-type query sequence from the host. (MS-Kermit also can emulate VT220, VT320 and several other types.) > Also, I wanted to know if Vt100 and Vt200/220 are much different. Are > there big differences between them or can they be summed up easily in a > reply? Since the introduction of the first ANSI-compatible DEC terminal, the VT100, Digital Equipment Corporation has been pretty good about making each new generation of video terminal products capable of a superset of the operations that the previous generation could do. Thus the VT100 could operate in either its ANSI style or that of the older, cruder VT52 product. The VT102 did what the VT100 did plus a few tricks. The VT125 did what the VT102 could do plus ReGIS graphics. (There were some other VT1xx models about which I know little.) Later, the VT220, VT240, and VT241 (there was no VT200 as such) added a good many capabilities (such as the 8-bit multinational character set), but there was a setup option to make it seem to be a VT100. (The VT240 and the VT241 differed only in whether a monochrome or color monitor was supplied.) One major change from the VT100 series was the keyboard layout, with the LK201 keyboard in the VT200 series adding numerous top-row special- function keys while omitting the single-purpose Escape key and a couple others. The LK201 also introduced the Compose Character key, which to this day remains shrouded in mystery. ;-) Some of the LK201 function keys sent codes to the host, while others had only local effect. When you put the VT220 into VT100 mode, three of the top-row function keys reverted to VT100 purposes, such as Escape, Linefeed, and Backspace. And the LK201 put the <> characters in the controversial B00 position, to the left of the Z. (This tendency was not just DEC's; at about the same time, IBM put \| in the B00 position on the keyboard of the original IBM PC. International standards often have the effect of making all nationalities equally disgruntled.) The VT300 series (VT320, VT330, and VT340) added some features and, to some extent, compensated for aspects of the VT200 series that users had complained about. Then there came the VT400 series, and the now-current VT500 series. There are various new features that have been introduced at each step, but if a host computer sends out a valid series of VT100 display codes, a listening VT510 will correctly format its screen display in just the same way the VT100 would. > Is there some reference out there that talks about vt220 features >_Additional_ to vt100, or should I simply treat it as completely different > and a new emulation? I suggest you connect by "anonymous FTP" to CS.UTK.EDU (if your machine is registered in the DNS); look in "pub/shuford/terminal" and retrieve the file "vt510_function_checklist.ps", a PostScript file that contains a good list of terminal features with some information on which terminals support them. [available from the DEC page at http://www.cs.utk.edu/~shuford/terminal_index.html ] But really, if you think your emulation is going to be used by any large number of people, you would do them a favor by also obtaining and reading the real documentation of the terminals you are trying to emulate. (It wouldn't hurt, either, to try out a real terminal of the intended type.) One cost-effective document is "VT220 Programmer Pocket Guide", part number EK-VT220-HR-001, $21.00 (US). From the 48-state United States, call 1-800/DIGITAL to order this. From elsewhere, dial +1 603/884-6660. Alas, the "VT510 Reference Manual" (EK-VT510-RM) will cost $220.00!

VT220's are nice terminals. You could bounce rocks off 'em. > S. Well, once I finally found the box with my null modem cables in it (in the process of moving, can't find anything) I hooked the terminal to my Linux box, and changed lilo.conf to tell the computer that the terminal was the system console. Fired up the terminal, worked perfectly. I was really worried about the backspace not working in local mode. I thought the terminal was responsible for all of that. Oh well, it works, and I appreciate the help. Now I know more about how the VT220 works. I also found that the VT220 has a composite output jack on the back! I got a little adapter at Radio Shack that went from the BNC to an RCA jack. I then hooked it to a T.V., and it worked pretty well, although the TV has lower resolution than the VT220. Just for fun, I plan to connect this thing to the big screen T.V. once it's out of storage. Now I can play 43" NetHack :). While I am on the subject of the VT220, I have noticed that when listing long directories, cat-ing readme files, or running certain programs, the text display gets messed up, and I get superfluous characters, text out of alignment and the like. Could this be caused by the termcap entry? Could it be that Slackware linux doesn't have the proper entry for a VT100? (I run it in VT100 mode, I may start using it in VT220 mode, but I was always told that VT100 mode was more compatible) Or could it be caused by the baudrate? I have both the computer and the terminal set up to talk at 19200 baud, and my serial cable isn't very long, so I don't really think it's a problem, but I can't be sure. Thanks!

The 'Compose' key is for creating high-order ascii characters, and other ascii characters not on the keyboard. To use it, you must operate the terminal in an eight-bit environment, and be using the VT in VT220 mode. Put simply, you compose an accented character by a two or three character sequence, e.g. for A-umlaut you would type COMPOSE A ", for c-cedilla type COMPOSE c , ... for GB pound sign it's COMPOSE l =, for Japanese yen it's COMPOSE Y =. Most of the accented characters are fairly easy to guess once you understand the principle of 'combining' the ascii characters. >Can I 'save' stuff to the >function keys so that I power up with Hayes AT commands on them? The contents of the function keys are host-writable, but the VT220 loses the settings when turned off. You could look at the ANSWERBACK field though. >Are there >any roms out there for Japanese characters sets? The character matrix on the VT220 is a bit too crude to allow much in the way of Japanese, as the chinese root symbols that most of Japanese starts words with are too complex to the represented properly.

DEC settled on an official definition of "VT100 compatibility" some years back. (For the curious, it exists as an internal-only document perhaps an inch thick that defines a model for a terminal and then the actions in all circumstances. The definitions are given in simple Pascal - which is actually executable. If executed, it gives you a slow implementation of a VT100-- slow because the point is clarity and ease of understanding, not execution speed or program size.) All DEC terminals that claim "VT100 compatibility" are tested against this spec, and must conform to it. As far as I know, all of them do. The actual spec for the "VT100" does not actually match the original VT100 terminal. Rather, the standard is really almost identical to the VT102, a later version. For the most part, the VT102 was the same as the VT100 with the AVO option (which gave you 24 lines in 132 character mode, rather than 12; and all four character special renditions - bold, blink, underline, reverse - rather than just one, which was either reverse or underline, depending on how you set the cursor display) and, I think, the printer controller and modem interfaces. The only significant features of the VT100 that I know of that were left out of the VT102 (and all subsequent terminals) were the user-controllable LED's on the keyboard and control of interlace mode. (The VT100 could run its display in either interlaced or non-interlaced mode. The choice could be made in SETUP or with an escape sequence. The original VT100 had 4 LED's on the keyboard, all under user control. Some versions of the VT100 series reserved some of the LED's for other indicators, mainly the state of modem lines; on these I think two user-controllable LED's remained. Later terminals dropped these LED's entirely.) Also, the VT102 omitted all the known VT100 "bugs", some of which had come to be seen as interesting "features" (for example, the "ring the bell forever" mode). By the way, the following things are not considered part of the VT100 speci- fication: - SETUP mode - On-screen appearance of characters. The fonts used are not specified, nor how the different character renditions are to be implemented (except that they are all to be visibly distinct, in all combinations). In particular, "bold" was implemented on the original VT100 series using greater beam intensity. The color VT240 used a different color. All recent terminals use an alternative font with more pixels turned on. - The configuration of the keyboard, beyond the requirement that there be some way to enter the entire 7-bit ASCII set. (The spec may not bother to say this explicitly.) -- Jerry ////////////////////////////////////////////////////////////////////////////// Newsgroups: comp.terminals,vmsnet.misc Path: cs.utk.edu!shuford Message-ID: <1p7s9gINNhvl@CS.UTK.EDU> References: NNTP-Posting-Host: carlsberg.cs.utk.edu Organization: University of Tennessee, Knoxville--Dept. of Computer Science Date: 29 Mar 1993 22:13:04 GMT From: shuford@cs.utk.edu (Richard Shuford) Summary: lacking in VT220 Subject: Re: VT100 features not in 220/320?

The major feature of the VT100 that people noticed being omitted from the VT220 was the Escape key. (Well, sort of. If you put the VT320 or VT220 into VT100 mode, you can use the F11 key of the keyboard as an Escape key, but then you can't use the new terminal's extra features. On the VT320, and I think also on the VT220, you can transmit an Escape character by pressing the key combination Control-3. You can also type Control-[, which is pretty much the definition of the Escape code.) In intention, anyway, the electronic features of new DEC terminals have generally been a superset of what the older products could do. -- ...Richard S.

I'm not sure what that is but from the sound of things you were lucky you didn't electrocute yourself. The monitor is either an Elkston or a Ball standard video monitor assembly, and should be simple for any qualified CRT technician to diagnose and repair or, more cheaply actually, replace. Don't mess around with these yourself as the high voltage can kill you. There is a VT1xx series technical (shop) manual; I have one but am not willing to part with it. You might consider chucking the whole thing and using a cheap IBM PC clone with VT1xx emulator software instead,. \/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/ Newsgroups: comp.terminals Path: utkcs2!darwin.sura.net!mips!spool.mu.edu!olivea !news.bbn.com!bbn.com!pdsmith From: pdsmith@bbn.com (Peter D.

Block mode lets you transmit a while block at a time rather than a character at a time, and use a built in editor (in the terminal) to do editing locally. This is for IBM mainframes and similar computers with a block-I/O mentality. The 131-ness is due to a chip which fits on the motherboard. If you remove the chip, you get a vt102 (it shows so in the setup screen). Important note: A vt102 is functionally similar (but not functionally identical) to a vt100.

The only VT-640 I know of was Digital Engineering's (NOT DEC's!) "RetroGraphics" add-on for DEC's VT100, which provided overlaid Tektronix 401x graphics emulation (and nothing else) on top of the VT100 text video. The nicest DEC "terminal" I ever used was their VS60 stroke-refresh work station (VR48 video, VT48 display processor as a second Unibus master). It was essentially upward compatible with the "VT11" (which went under several guises).

This is easy to do with the DECterm keyboard customizations options, and is quite natural for those of us who were learned to type on computers before the larger international keyboards were introduced. The one problem is that other windowing programs don't necessarily pick up those resources, so you may need to go into the resource files and set them manually; even so, there are probably some X applications that just ignore those resources. I don't let keyboard differences fluster me, even though I touch type, but I'm the exception, not the rule. If your users are just using DECterm, they shouldn't have any problems with this setup.

There are a few possibilitis: 1) Set your terminal to VT52/100 Emulation mode. Then your ESC/BS/LF keys work but the other F-keys are dead. 2) Type Ctrl-3. That works always. If you have an american keyboard, Ctrl-[ works also. 3) I don't know, if it works for the vt220, but the vt320 and vt420 can be programmed (Setup Keyboard) that the american ~` key sends ESC. This works only, if you have an american keyboard installed (bug or feature ?). 4) You can programm any Function key in conjunction with Shift as user-defined. If you want to use Shift-F11 as ESC-Key in VT220/320/420-Terminal mode then let your host send "DCS 1;1|23/1B;24/08;25/0A ST" where DCS=ESC P and ST=ESC \ in 7bit mode. This puts BS and LF on F12/13 as well. On most compatible vt-terms the string "DCS 1;1|43/1B;44/08;45/0A ST" works for the unshifted F-Keys but not on DECs :-( .

I wanted to (and did) hook up a VR201 to a GIGI. The pinout is standard from DECmates to workstations; however note that mono only systems don't use the colour lines and vice-versa. There's only one "monitor present" line (tied to ground in the monitor, or in the connector block for those monitors that use BNC connectors), so a machine can't tell if there's a VR201 or a VR241 at the other end. (Actually, if the thing at the other end draws power, it's a 201, since the 241 has its own power supply, but I don't believe that's implemented anywhere.) Thus, you can (in theory at least, ie assuming the cable brings does the right thing with all the lines) use a VR201 with the same cable on a VT240, DECmate or Rainbow; likewise with the VR241. The cable is not so much a "DECmate" (or whatever) cable as a "VR201" (or VR241) cable. The VR201 cable is the same pinout at both ends -- you can bang two of them together if you need a longer cable to the monitor/keyboard. (I think it brings the colour lines out as well (which the VR201 ignores), but I'm not sure.) From your commemts below, it sounds like while the VR201 cable is pretty much standard across the board, the 241 cables have some bogosities in their implementations. >My experience with the DM II (as opposed to the III and III+) is that the >VR-241 doesn't work on it at all. Note that the recommended configuration That will be because the VR241 doesn't listen to the mono line, and the mono socket of the DECmate doesn't put anything on the colour lines. Try re-wiring the mono line from DECmate to the green (I think -- whichever one generates the sync) line of the monitor. >I have used this cable on an actual VT-240.

(Does it return a terminal escape >sequence that is different if a VR-241 is installed?) Nothing changes on a VT240 whether there's a mono or colour screen on it; it doesn't detect the 241. Tha name "VT241" is ordering information only; what you got when you ordered a VT241 was a box with "VT240" on the front and a VR241 on top of it. The 240 base unit generates both colour and mono output, regardless of what's on the other end of the cable, and the ID sequence is identical. >Anyway, the DM II cable is different!

It's always the full width of the screen (though that restriction was eventually removed in the VT400 series of terminals), but it's otherwise very much a subwindow. Once you've set a scrolling region, most (not all) actions you can take are limited to that subwindow. You scroll the region just as you would scroll the entire screen: By inserting or deleting lines. If you leave Cursor Relative mode set (as it is by default), cursor addressing is relative to the scrolling region. Many screen-oriented programs that are intelligent enough to deal with different-sized windows will run happily within the scrolling region, never knowing the difference. (The limitation is that sequences that affect the entire display, such as Erase in Display, will not respect the scrolling region's boundaries.) -- Jerry ----<>----<>----<>----<>----<>----<>----<>----<>----<>----<>----<>----<>---- Newsgroups: comp.terminals Path: cs.utk.edu!gatech!howland.reston.ans.net!zaphod.mps.ohio-state.edu !menudo.uh.edu!uhdvx3.dt.uh.edu!0758cs11 From: alex@dt.uh.edu (Alexandre Khalil) Subject: Re: Hooking a vt220 to a modem in a PC Date: 8 May 1993 11:42 CST Organization: University of Houston-Downtown Lines: 30 Sender: 0758cs11@uhdvx3.dt.uh.edu (Alexandre Khalil) Distribution: world Message-ID: <8MAY199311424154@uhdvx3.dt.uh.edu> References: NNTP-Posting-Host: uhdvx3.dt.uh.edu Keywords: vt220 modem X-Lunar-Date: 7 days, 1 hour, 52 minutes since the first quarter of the moon News-Software: VAX/VMS VNEWS 1.42 In article , you write... >I am connected today to a vax via a modem+pc computer .

Yes, though I would not recommend it: I have both a VT220 and a VT320 and I prefer using the 14" screen of the 320 or of the PC, rather than going down to 9" on the 220. All you need to do this is an external modem -hopefully, a recent Hayes compatible one- and a parallel printer cable.

And the documentation only seems to describe individual escape > sequences, not what order to use them in. The VT100 scrolling region feature is peculiar, but it is very useful in implementing "open-line" and "kill-line" functions on a real VT100, which does not otherwise have such functions. The way it works is that one places the cursor in the desired region, establishes the scrolling region via the escape sequence, and then further received data is constrained to that scrolling region instead of the whole screen, while data already on the screen outside the scrolling region stays fixed. Thus, if you generate output into the scrolling region that would cause whole-screen scrolling under normal circumstances (e.g. line-feed at bottom of the region), the text within the scrolling region will scroll. Data that scrolls "off" the region is discarded, and lines that scroll "onto" the region start out empty. Not all so-called "VT100 emulators" properly emulate this, nor indeed several other, features of a genuine VT100. Almost no emulator provides smooth scrolling, which on a real VT100 is pretty nifty (assuming one's host is properly honoring DC3/DC1 flow control from the terminal). ---o---o---o---o---o---o---o---o---o---o---o---o---o---o---o---o---o---o--- Newsgroups: comp.terminals,biz.dec,comp.org.decus,comp.sys.dec Path: cs.utk.edu!gatech!howland.reston.ans.net!usc!elroy.jpl.nasa.gov!decwrl !pa.dec.com!uniriv.vbo.dec.com!kaiser Organization: DEC Technology Integration Group Sender: kaiser@mammal.vbo.dec.com (Pete KAISER) Message-ID: <1tqdn8$qtu@usenet.pa.dec.com> Reply-To: kaiser@uniriv.vbo.dec.com NNTP-Posting-Host: mammal.vbo.dec.com Keywords: terminal, VT Date: 24 May 1993 12:06:00 GMT From: kaiser@uniriv.vbo.dec.com (Pete KAISER) Subject: VT50, VT52, VT55 being retired I've just received an internal publication dated 17 May 1993 giving the sad news that the VT50, VT52, and VT55 are being retired from sale by Digital, effective immediately.

Probably not. The DEC "GPX" video standard uses timing that's different from anything generated by any PC (or Mac) video that I've heard of.

With a real VT100, this is done by repainting the entire screen. Period. Later DEC terminals, including I think the VT102 (which really defines "VT100" and has for years) - but certainly the VT200's - have the ability to insert spaces on a line, shoving the rest of the line over. As I recall, you can only insert at the left, with extra characters at the right vanishing. So you can insert the necessary spaces, then paint the new leftmost characters. This can only be done one line at a time, and probably isn't worth it in most cases. You have to go all the way to the VT400 series to get the ability to really scroll a region of the screen horizontally. -- Jerry \/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/ Path: cs.utk.edu!ornl!rsg1.er.usgs.gov!darwin.sura.net!gatech!swrinde !cs.utexas.edu!uunet!ug!rief Newsgroups: comp.os.vms Subject: Re: portable VT100/200 type terminal available?

The CAD function is used to allow updating of displayed data without retransmitting the complete page. For example, if the cursor is located in character location 55 of line 18 and the operator wishes to update information beginning at character location 35 of line 9, transmission time would be greater if the operator used the cursor control characters, e.g., "cursor up" and "cursor left" to move to the new location. By using the CAD function and the codes shown in Table 3-3, the cursor can be quickly directed to any of the 1440 character locations on the screen. A reduction in generation time is especially noticeable when CAD-generated data is retrieved from memory. CAD is received by the VT05, and the next two data words are interpreted as the Y- and X-address. The Y-data word presets the Y-address counter to the selected character line, and the X-data word presets the X-address counter to the selected character position in the selected line. Once the cursor is moved to the new location (or address), the cycle is complete and the next data word received will perform its normal function. --end quote-- There is no termcap entry for a 'vt05', but there could be many reasons for that. I have no idea how many people shelled out the $2795 list price for a VT05 rather than sticking with their teletypes. Bill Joy used an ADM-3a to develop vi and what would eventually become termcap. ~Paul ////////////////////////////////////////////////////////////////////////////// Newsgroups: comp.terminals Path: cs.utk.edu!gatech!howland.reston.ans.net!noc.near.net!uunet!pipex!uknet!bradford.ac.uk!M.T.Shipley From: M.T.Shipley@bradford.ac.uk (MT SHIPLEY) Subject: Re: VT100 font?

Something's missing there -- that's not a complete, legal ANSI escape sequence. ANSI uses several character ranges during CSI and DCS sequence parsing. The ranges 20-2F, 3A and 3C-3F are used for application-specific flags. 30-39 are the parameter values. 3B is the parameter separator. The final character -- sometimes called the sequence terminator -- must be in the range 40-7E.

Can someone please tell me the escape sequences used by a VT420 and SSU or a terminal terminal to perform the multi-session handshaking? They are not "escape sequences," a term with a specific meaning defined in ANSI X.34 (I think that's the number). The commands use an entirely different format with a different introducer character; they exist at a different level in the protocol stack. (The protocol involved is called TDSMP, for Terminal Device Session Management Protocol. TDSMP commands can actually appear in the middle of an escape sequence; when the session is resumed, parsing of the escape sequence takes up where it left off.) I suspect they are documented in the VT420 programming reference manual, but I would like to avoid the expense and lead time of ordering it for this "simple" need. [EK-VT420-RM is list $C 173] Don't bother ordering it for this purpose; the TDSMP commands are not documented. I am trying to tailor a PC communications package to permit it to use a TCP/IP DECserver connection with ANSI emulation to one host, and VTxxx emulation to another host. Be aware that TDSMP is protected by patents. (Yes, not just in the US; in Canada and much of the rest of the world, too.) While it's true that a number of third parties appear to have reverse-engineered the protocol and are selling products based on it without public challenge from DEC, that doesn't mean DEC won't change its mind - it's got a history of aggressively defending its intellectual property rights. -- Jerry [Co-inventor of TDSMP, who may not necessarily agree with how DEC manages it, but is telling you the facts as he knows them.] \/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/ Newsgroups: comp.sys.dec,comp.org.decus,alt.folklore.computers Path: cs.utk.edu!emory!sol.ctr.columbia.edu!spool.mu.edu!uwm.edu !post.its.mcw.edu!not-for-mail X-Newsreader: TIN [version 1.2 PL1] NNTP-Posting-Host: post.its.mcw.edu Message-ID: <2dkvs7$g9b@post.its.mcw.edu> References: <1993Dec2.012135.2584@sequent.com> Organization: Medical College of Wisconsin; Milwaukee Wisconsin Date: 2 Dec 1993 08:59:19 -0600 From: "Kent C.

From the marketing literature... The short story is, that "Dorio" is a new "brand name" (marketing speak) for this terminal. The VT510 and the Dorio were announced in Sept '93. The VT510 is for traditional Digital customers and the Dorio is for the "ASCII" terminal world. There are some h/w and s/w differences between VT510 and Dorio, but they are very similar products. The Dorio is: - Built by Digital Equipment Corp. - A new "brand name" (marketing speak) - It is an "ANSI/ASCII" terminal. ie. it has traditional Digital ANSI standard terminal modes VT320, VT220, VT100, VT52 and (new for Digital) ASCII terminal emulations: WYSE 60, PCTerm, WYSE 50, WYSE 150/120, Televideo 950, 925, 910+, ADDS A2 and SCO Console. - It was designed to replace existing terminals found in UNIX, Pick, multiuser DOS, etc. "ASCII" environments - Keyboard and character set support for 27 languages - It is *not* a repackaged VT420 (Dorio is new hardware) - It has new features specifically for VARs like . A Power Up screen banner (advertise your name here) . A completely reprogrammable keyboard (onboard Define Key Editor) (Set-Up or Num Lock key can be disabled to prevent user error, any key can be a Function key) . Local user functions: Clock/Calculator . Local Program/debug functions: Show character sets, Show control chars . Snap-in ROM cartridge for bug fixes and custom code - SCO Console mode maps to the "ansi" terminfo found on SCO UNIX, but it works with other UNIX also.

Well, no. A VT420 *is* VT100-compatible. Any program that queries the terminal itself and then doesn't know enough to handle a VT420 properly is simply wrong. I thought we'd retired code like this 10 or 15 year ago. This used to be a major pain in the neck - code would run on a VT100 but not a VT102 because the VT102's id sequence was (just a bit) different. If I go into the Set-Up menus on the VT420 and select the General Set-Up screen, I can change the Terminal Mode from "VT420 mumble" to "VT100". This can also be done via software but does not satisfy the requirements of the software offering me menu displays because it still tells me that the terminal is NOT VT100 compatible. Back into the Set-Up menus (same screen), down towards the bottom of the screen is an item that says "VT420 ID" - this needs to be changed to "VT100 ID" - which I can do via the Set-Up but would really like to do this via a program... So, after all that - how do I (or can I) change this "VT420 ID" to "VT100 ID" via software? I have RTFM but - no luck... I don't believe you can. I don't have any VT420 documentation here, but this was not a software-settable parameter on earlier terminals. (If you think about it, just how much sense does it make for software to set it? The software would first have to know that it was talking to something that was not a VT100, then tell it to lie. Yes, I know, *some* of the software would know, and it would ask the terminal to lie to *other*, broken software. Sigh. You really should complain loudly to your vendor about this; getting it right isn't hard, and after all these years there's really no excuse.) I gather many terminal settings that have traditionally not been software- settable have been made so in the VT510. It's possible this is among them. -- Jerry \/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/ Newsgroups: comp.terminals Path: cs.utk.edu!emory!europa.eng.gtefsd.com!howland.reston.ans.net!wupost !decwrl!pa.dec.com!src.dec.com!crl.dec.com!nntpd.lkg.dec.com !hannah.enet.dec.com!hedberg Organization: Digital Equipment Corporation, Marlboro, MA Message-ID: <2sodbm$nmm@nntpd.lkg.dec.com> References: <2rtdol$gvi@usenet.INS.CWRU.Edu> Date: 3 Jun 1994 23:11:50 GMT From: hedberg@hannah.enet.dec.com (Bill Hedberg) Subject: Re: CNTL-S Pass-Through ?

Pressing the "Hold" key on a VT320 or VT510 inhibits the terminal firmware from processing characters in the communication buffer. If the host continues to transmit data while Hold Screen is enabled, eventually the comm buffer fills, which triggers the XOFF character. Pressing Control+S will cause the terminal to transmit a Control-S (XOFF/DC3) character. The VT510 has a local Define Key editor which allows you to program a key to transmit Control-S. Example, Enter Set-Up, go to the Define Key Editor in the Keyboard menu, enter the editor. Press the key you wish to assign Ctl-S to, define it as a User Defined Key (UDK). Press Ctl-S at the UDK line prompt. Arrow down and Save it if you wish to have it defined this way upon Power Up. As Patric Davies points out in his reply, getting the terminal to transmit Control-S is only half the problem. You must also configure the host to pass Control-S on to the application. This means that you cannot use XOFF/XON software flow control. - Bill \/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/ Newsgroups: comp.terminals,comp.emacs Path: cs.utk.edu!gatech!newsxfer.itd.umich.edu!gumby!yale!yale!yale.edu !noc.near.net!genrad.com!genrad.com!not-for-mail Organization: GenRad, Inc.

I'm not sure whether or not this is the only difference, but the VT102 has the capability of doing line and character inserts and deletes, functions which are missing from the VT100. In order to mimic line inserts or deletes on a VT100, it is necessary to define a scrolling region from the line of interest to the bottom of the display, and then scroll that region either up or down, depending upon whether you want to delete the line of interest or else push down that line (and all those below it) in order to insert a new blank line. I have no such clever work around for the absence of the character insert/delete (but, then, I've never looked for one). By the way, in my experience it seems that most terminal programs which claim to be VT100 (not VT102) emulators also perform the line/character insert/delete functions.

The VT320 supports 8-bit Multinational characters (ISO Latin-1); provides 105 key keyboard similar to Enhanced PC (separate top row function keys, editing and numeric keypads); provides a 25th status line; Terminal State Interrogation (host can read back almost all terminal settings); soft character sets; and programmable top row function keys. Physically the VT320 is much smaller, offers a higher resolution display, and runs faster. - Peter \/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/ Newsgroups: comp.terminals,comp.protocols.kermit.misc Path: cs.utk.edu!not-for-mail Followup-To: comp.terminals,comp.protocols.kermit.misc Distribution: world Expires: 31 Dec 1994 22:11:33 GMT Message-ID: <39o5aqINN164@cetus2e.cs.utk.edu> References: <39nbr2$rkh@kronos.fmi.fi> NNTP-Posting-Host: cetus2e.cs.utk.edu Summary: there are 2 cases, according to VT330/340 documentation Keywords: DECRQM, DECRPM, VT300, VT330, MS-Kermit, mode, setting, report Organization: University of Tennessee, Knoxville--Dept. of Computer Science Date: 8 Nov 1994 10:26:18 -0500 From: shuford@cs.utk.edu (Richard Shuford) Subject: Re: Incorrect response to request of terminal mode status (DEC modes) In article <39nbr2$rkh@kronos.fmi.fi>, hurtta@dionysos.fmi.fi (Kari E.

This is very dependent on which exact VT terminal you're talking about. For the VT300 series, there is no way to incorporate the status line as part of the main screen, although some implementations (eg, DECterm, a VT320-level implementation on DEC workstations) allow you to select the status line or not, and also allow you to set the size of the main screen (up to perhaps 72x132 or so being reasonable if you have a 1280x1024 screen), which gives you much the same capability that's being asked for here. However if the host software requests a status line, the DECterm will helpfully create it for you (keeping your main window the same size but possibly making the entire window too big to quite fit on the screen if you've made it big). The VT420, on the other hand, actually does allow you to combine the status line with the main screen, so that you get true 25x80 screen addressing but no status line. It also allows you to set the terminal in 36 or 48-line modes, but I think those include a separate status line. I don't know offhand what the VT420 does with the "Select Status Line" commands if it's in 25x80 mode; the terminal I've usually experimented with for such questions is on the other side of town, and the documentation around here is vague on the subject. The subject of compatibility with VT-series status lines is rather subtle. I have yet to see any terminal emulator, commercial or otherwise (including Kermit and even DEC's Pathworks terminal emulator, I might add) that quite gets it all right. Bruce C.

Shuford Subject: Re: My vt320 termcap file Regarding the F5 key: Somebody else may point this out, but on a real DEC VT220 or VT320, the first five top-row function keys are intended primarily as local functions, not as things a remote application program can sense; indeed F1 through F4 don't send anything to the host at all. On a VT420 (for which I've got the manual here) KEY FUNCTION --- ------------------------------------------------------------ F1 Hold (controls scrolling via XON/XOFF). F2 Local Print (prints screen to locally attached printer). Shift-F2 (on VT320) prints graphics and text. Control-F2 toggles auto-print mode. F3 Enter terminal's setup mode. F4 Switch sessions (for dual-session terminals). Control-F4 splits screen (for dual-session terminals). F5 Break (sends long serial break). Shift-F5 drops DTR to disconnect a modem. Control-F5 sends the terminal's answerback message to the remote host. However, the more recent VT420 product can be configured (by use of the setup menus) to have the F1 through F5 keys really send a code sequence to the host instead of performing the local operation. The code sequences are of the form Esc [ 1 2 ~ in 7-bit communication environments or CSI 1 2 ~ in 8-bit communication environments.

To recover from this condition, you have to log out, turn off the terminal, wait 10 seconds, turn on the terminal, and then make F3 the very first key you press after it has initialized. Then the terminal enters setup mode, and you can change the use of F3 (or other parameters).

Since the VT510 hardware was designed, many high speed modems have adopted CTS/RTS flow control. This makes sense for modems. It is less obvious for terminals that need to work in existing environments. Most high speed modems use the Hayes AT command set and no longer require DSR/DTR control signals for connection management. Thus you can often wire the DSR/DTR signals from the terminal to the CTS/RTS pins of the modem to take advantage of hardware flow control. Future VTs may include a CTS/RTS selection depending customer interest and cost trade-offs. - Peter Video Terminals Business Group Components & Peripherals Digital Equipment Corporation \/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/ Newsgroups: comp.os.linux.help,comp.os.linux.admin,comp.terminals Path: cs.utk.edu!gatech!bloom-beacon.mit.edu!uhog.mit.edu!news.mathworks.com !transfer.stratus.com!xylogics.com!Xylogics.COM!carlson Organization: Xylogics Incorporated Message-ID: <3egoee$m73@newhub.xylogics.com> References: <3d8o50$h96@usenet.rpi.edu> <3egahh$acf@kronos.fmi.fi> Date: 5 Jan 1995 12:24:46 GMT From: carlson@Xylogics.COM (James Carlson) Subject: Re: Backspace in Linux ?

The VT220 command ESC SP F (called S7C1T in the DEC documentation) tells the terminal to transmit the 7 bit equivalents for the 8 bit C1 codes to the host, both for command responses (like the response to CSI c), and for function keys which return C1 codes. Likewise, ESC SP G (S8C1T) tells the terminal to transmit 8 bit C1 codes if the terminal has an 8 bit data path to the host. (The command has no effect if the host port is set to 7 bit mode.) These commands do not affect the interpretation of received codes. To do this, you'll have to set the terminal into 7 bit / mark parity mode. |> If anyone kows, please email to me (the prefered way) or simply |> followup to this group.

On VT420's and above, the 25th line can be used as either a status line (logically a separate display window) or as part of the main display window. The VT420 can also be configured with more lines, for example, a 36-line mode, but the more dense displays get rather unreadable because the monitor itself is still the same size as the other low-end VT monitors. > b) If (a) == "Yes" then does that line scroll up with the rest of them if the > cursor is directed there? Or does the cursor 'stick' to the 25th line? On the VT420's and above, if you have selected the 25th line to be part of the main display, then it will scroll with the other 24 lines on the display. If you have selected the 25th line to be a status line, then it will not scroll with the other 24 lines on the display. The normal behavior for the DEC VT-class terminals if a cursor sequence tries to place the cursor on any line beyond the end of the main display window (that is, on the 25th line or below in most cases) is to place the cursor at the same column position on the last line of the window (the 24th line in most cases). As I understand Kermit's behavior, it isn't strictly compatible with the DEC hardware; but there are other terminals out there that do behave similarly to Kermit. I wouldn't be surprised if the problem is that some of the software is doing a terminal type query and setting itself up according to what it receives from that - there's a fair amount of software in the DEC world that does that (even though you're theoretically supposed to take the OS's word for the terminal type).

The VT220 and VT320 are similar except the VT320 includes 1) ISO Latin-1 and a User Preference Supplemental Set (in addition to DEC MCS). 2) 25th status line. 3) Terminal State Interrogation - the host can read back anything it can set. These three features define "Level 3" or VT300 compatibility. The VT320 also displays more scan lines (300 versus 240) and lacks a video output jack. The VT330 is a very different design that includes ReGIS, SIXELS, and TEK 4010/4014 graphics, a mouse port, dual sessions, horizontal or vertical split screen, and a bunch of other stuff. The VT330 displays 500 scan lines (800x500 resolution). - Peter, W8PS [I know cuz I helped design them...] \/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/ Newsgroups: comp.terminals Path: cs.utk.edu!stc06.ctd.ornl.gov!fnnews.fnal.gov!uwm.edu!spool.mu.edu !howland.reston.ans.net!news.sprintlink.net!uunet!news1.digital.com !pa.dec.com!mrnews.mro.dec.com!refine.enet.dec.com!mcdonald Organization: Digital Equipment Corporation Message-ID: <3lp24m$sln@mrnews.mro.dec.com> References: <3jof0pINNrad@duncan.cs.utk.edu> <3jq1ab$ouf@kronos.fmi.fi> <3k4jim$ci7@news.primenet.com> <3kkaoq$t4g@mrnews.mro.dec.com> Date: 3 Apr 1995 14:53:10 GMT From: mcdonald@refine.enet.dec.com (.)

In terms of the VT100, the VT102 included AVO (which gave you the four standard video attributes as well as the full 24 rows in 132 column mode; the VT101 was the second-generation family member *without* AVO). All the "second generation" terminals were "bounded": They couldn't be upgraded in any way. (The original VT100's could accept some options, and had room and power in the box for some fairly complicated stuff - the VT103 was a VT100 with an LSI-11/23 on a Q-18 bus, really an early PC.) If I remember right - it's been years - the VT102 added the Insert Line and Delete Line commands to the VT100 set. On a VT100, you could, indeed, simulate these using scrolling regions. In practice, it's almost impossible to find any terminals or emulators that do a "real VT100" - they all do a VT102. In fact, the official *definition* within DEC of "VT100 mode" is really "VT102 mode" - that's what you get in a VT200 or later DEC terminal when it's in VT100 mode. (I suspect the only reason IL/DL weren't in the original VT100 is last-minute lack of code space - something had to go, and these could be emulated easily with scrolling regions.) -- Jerry \/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/ Newsgroups: comp.protocols.kermit.misc Path: cs.utk.edu!cssun.mathcs.emory.edu!hobbes.cc.uga.edu !news-feed-1.peachnet.edu!gatech!swrinde!cs.utexas.edu !news.sprintlink.net!news.indirect.com!monty Message-ID: Sender: usenet@indirect.com (Internet Direct Admin) Organization: Internet Direct, indirect.com Lines: 57 References: <3nmst7$q8g$1@mhafc.production.compuserve.com> <3no582$lhc@apakabar.cc.columbia.edu> X-Newsreader: TIN [version 1.2 PL2] Date: Mon, 1 May 1995 05:09:42 GMT From: monty@indirect.com (Jim Monty) Subject: Re: TELNET VT220 Support On 27 Apr 1995 13:12:34 GMT, Frank da Cruz (fdc@watsun.cc.columbia.edu) wrote: > > In article <3nmst7$q8g$1@mhafc.production.compuserve.com>, > Paul Taylor <75014.216@CompuServe.COM> wrote: > > > >Will the VT220 TELNET TCP/IP support in kermit support terminal > >escape sequences for foreground and background processing?

This is just a stab in the dark, but perhaps what Paul Taylor is referring to when he speaks of the VT220's "foreground and background processing" and "pop up windows" capabilities is actually the multiple session and windows capabilities of the DEC VT420 terminal. The VT420 allows one to run two sessions at the same time, to toggle between them with the F4 (Session) key, and even to cut and paste text between sessions (windows). To do this, the terminal must be connected to the host or terminal server using two cables, or to a terminal server that supports multiple sessions, or to a host running Digital Equipment Corporation's Session Support Utility (SSU). If you absolutely, positively can't have a personal computer and a terminal emulator (Kermit!) on your desktop, then a VT420 is the model terminal you beg for. What Mr. Taylor should know is that, whereas the VT420 allows only two simultaneous sessions, Kermit supports six simultaneous TCP/IP connections, even to the same host. (At least MS-DOS Kermit 3.14 does. I don't know about the OS/2 version.) One can easily toggle between these multiple sessions by pressing Alt-n (\KnextSession). (Again, I only _know_ this is true for MS-DOS Kermit 3.14. Check the documentation for your flavor of Kermit.) What _is_ missing from Kermit is the capability to easily cut and paste text between "windows" (sessions). For the model of how this feature, if implemented in Kermit, might ideally work, sit at a DEC VT420 terminal and use the F1 (Copy), Select, Remove, and Insert keys to cut and paste raw ASCII text. (VT420 terminals are designed for those who can type. Don't bother looking for a mouse port.) [C:\] MS-Kermit>set opinion-mode on, connect I, Jim, will continue to use MS-DOS Kermit and support its development through the purchase of supporting documentation even if the capability to cut and paste text within and between sessions is never added to the program. But I shall be very pleased if it is.

For those who don't know about the GIGI, a little bit of history: Also known as the VK-100, the GIGI was DEC's Apple II: it had Basic (I think from Microsoft) in ROM, and looked about like an Apple II. There was supposedly an ability to download and upload BASIC programs, but so far as I know, VMS never supported that, except through user-written software. In about 1982 or 1983 we got several of them when I was at Kalamazoo College. Yup. The GIGI was intended for the education market. They took an external monitor, with RGB cables. As I recall, the resolution was at least VGA-equivalent, years before IBM did VGA, and they had THREE-BIT color: black, white, red, green, blue, cyan, yellow, and magenta. The funny thing was that we got them as part of a promotion, with a discount on some nice BARCO monitors. The discount was in the form of a coupon! It was a very handsome 8 x 10 certificate, but it was a coupon, nonetheless! I had the impression that the ReGIS graphics language was invented as part of the GIGI project, although it did show up on several later terminals. Can any of the Digits on this discussion confirm or deny that? I'm 99% sure this is correct. The first versions of TPU, with the EDT-emulator, half-way supported them, but it was not a happy match. The GIGI had an "almost VT100" terminal emulator. It was off by enough to give many programs headaches. They were pretty much an orphan product at birth, but they did have the effect of making me think poorly of the first Macintosh as a graphics DISPLAY (512 x 384, ONE-BIT), since I was slow understanding the issue of a graphical USER INTERFACE :-( It has been a while since I thought about the GIGI! Likewise! The GIGI was not what anyone would call a success - DEC gave away a good number of them, but it's a fair bet they never sold enough to make back the costs. It was a product that was a bit ahead of its times, and was also another case of DEC not having the foggiest notion of how to market a clever product it had managed to build. -- Jerry \/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/ Path: cs.utk.edu!gatech!swrinde!ihnp4.ucsd.edu!mvb.saic.com!info-vax From: Jerry Leichter Newsgroups: comp.os.vms Subject: Re: GIGI terminals Message-ID: <9506021839.AA17916@uu3.psi.com> Date: Fri, 2 Jun 95 14:31:03 EDT Organization: Info-Vax<==>Comp.Os.Vms Gateway X-Gateway-Source-Info: Mailing List Lines: 56 ...The VT125 was strange in lots of ways. The RGB output carried only the graphics video, while its built-in monochrome display mixed the graphics video with the standard VT100 character-cell video. (This is different from the GIGI -- using the GIGI in "character mode" caused writes to the graphics bitmap.) Had a very limited color palette and map, too -- you got to use a whopping four colors out of 64 available. The original VT100 was much more than a terminal - it really was a base display system. There was room and power in the box to add all kinds of interesting things. At one extreme was the VT103, which put a whole Q-bus backplane and an 11/23 inside the box. There weren't any disks small enough to put in there at the time, but everything else needed for a "PC" was there. I've still got one - long story. The VT125 was a similar design. The VT100 remains unchanged - the logic remains in the two-chip DC-something set, it has its own memory, its own D/A converters, etc. The graphics part of the VT125 is a completely indepen- dent processor. As I recall, it hooks into the incoming line in front of the VT100, and scans the data stream for the escape sequence that enters ReGIS mode. Then it takes over, grabbing characters until the ReGIS command to exit back to text mode arrives. At the other end, the VT125 has its own screen bitmap, and its own D/A conver- ters. An analogue mixer combines the signals from the text and graphics pieces. This design has some handy features. For example, you can scroll the text UNDER the graphics without affecting the graphics - very handy for debugging. People got used to this, and used it - assuming, for example, that clearing the textual data would leave the graphics image unchanged. They also made assumptions about the size and positional relationships between the text and graphics images, using textual data to anotate graphics images. All these assumptions were invalid on every later ReGIS implementation - all later implementations used a common bitmap for text and graphics. Many ReGIS-using programs failed to work properly on VT240's as a result. GIGI's also used the common bitmap approach, but they and VT125's were used by disjoint groups of people, for the most part, so the incompatibilities weren't obvious earlier. As to the four colors: It's hard these days of multi-megabit chips to imagine just HOW much memory COST in those days. I think the VT100 and VT125 use 8 Kbit chips! That's why AVO was a (moderately expensive) option on the origin- al VT100: All it added was a bunch more memory. Two bits per pixel was the limit within the VT125's cost budget. (By the way, you of course got your 4 colors on the "graphics" plane, plus the 4 white intensities available on the "text" plane - yes, "bold" on the original VT100 wasn't implemented by using a different "thicker" character bitmap, but by turning the beam up higher. The reverse video background was a low-intensity white. I think bold plus reverse used the "normal" foreground intensity. The actual brightness levels were quite precisely specified and controlled (relative to the general screen brightness, of course - you could change that) - one of the high-cost individual components in a VT100 was the high-precision resistor pack used to implement the voltage divider that defined the screen intensities.) -- Jerry \/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/ Newsgroups: comp.dcom.modems,comp.terminals Path: cs.utk.edu!willis.cis.uab.edu!news.ecn.bgu.edu!vixen.cso.uiuc.edu !howland.reston.ans.net!news.sprintlink.net!news.bluesky.net !news.mathworks.com!news.kei.com!nntp.et.byu.edu!netline-fddi.jpl.nasa.gov !hudson.lm.com!newsfeed.pitt.edu!dbisna.com!psinntp!psinntp!psinntp !news.nyc.pipeline.com!news.cs.columbia.edu!news.columbia.edu !watsun.cc.columbia.edu!fdc Organization: Columbia University, New York City Message-ID: <3ral47$qml@apakabar.cc.columbia.edu> References: <3qig7i$mrn@news.primenet.com> <3r56dh$vkn@mips.pfalz.de> NNTP-Posting-Host: watsun.cc.columbia.edu Date: 9 Jun 1995 23:22:47 GMT From: fdc@watsun.cc.columbia.edu (Frank da Cruz) Subject: Re: VT220 terminal and 14.4 modem, bad chars and dropped data In article <3r56dh$vkn@mips.pfalz.de>, Christian Weisgerber wrote: : > > I pulled a vt220 terminal out of the trash and hooked it up to a 14.4 : > > modem (Practical Peripherals PC144MT) to use for dialing in to the : > > campus unix boxes.

[20 milliamp] This is for an old interconnect standard, going back to teletype days. The electrical spec was: The sender must ensure that, when a signal is present, 20mA of current flow at the receiver. (Actually, "sender" and "receiver" is incorrect terminology - there was an "active" and a "passive" end, each of which could play both roles.) In teletype days, the sender might put tens or even hundreds of volts across a long line to ensure the 20mA flowed at the receiver! There was no physical connector spec for 20mA in general, but DEC used small flat white connectors for 20mA devices. They were made (originally?) by Borg, and were always known simply as "Borg connectors". They had a latching mechanism which was a real bitch to get loose - painful on the hands. I think 20mA support was a VT220 option - it was a dying standard. I don't think any later terminals supported it. > 2. BNC ? socket above RS-232.

The main difference seems > to be in the generation of escape sequences for the keypad, but I don't > know if this is a limitation in Microsoft's implementation. The VT102 was a member of the "second generation" of the VT100 family. The original VT100 was sold with a number of options that could be inserted into the box. The most significant was the AVO, or Advanced Video Option, which was pretty much just extra memory. The base VT100 supported a 24x80 mode and a 14x132 mode. It supported normal text plus one video attribute, which could be either underlining or reverse-video - which one you got depended on whether you selected an underline or box cursor. AVO gave you 24x132 mode and the full four video attributes (underline, reverse, bold, blink). The VT100 also had a modem control option, providing extra RS-232 signals. The VT102 was a closed system (no options) which provided the equivalent of a VT100 plus AVO plus (I think) modem control. It also added one or two new commands - if I remember correctly, "Insert Line" (open a new line, scroll stuff below it down) and "Delete Line", and perhaps "Insert" and "Delete Character in Line". DEC many years ago *defined* "VT100 compatibility" as "equivalent to a VT102". All subsequent DEC products that claimed VT100 compatibility actually supported the full 24x132 display mode, four video attributes, and the additional commands. (Modem control is a separate issue - "VT100 compatibility" is usually taken to refer only to *software* compatibility.) As far as I know, the industry has pretty much followed DEC's definition, except that many terminal emulators are incapable of properly supporting the 132-wide mode due to limitations of their displays. There is absolutely no difference between the keypads of VT100's and VT102's. -- Jerry \/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/ Newsgroups: vmsnet.pdp-11 Path: cs.utk.edu!cssun.mathcs.emory.edu!swrinde!cs.utexas.edu !howland.reston.ans.net!agate!dog.ee.lbl.gov!news.cs.utah.edu !cc.usu.edu!ivie Message-ID: <1996Aug2.100415.83475@cc.usu.edu> References: <199608011904.PAA24306@bronze.lcs.mit.edu> Organization: Utah State University Date: 2 Aug 96 10:04:15 MDT From: ivie@cc.usu.edu (Roger Ivie) Subject: Re: Intel inside In article <199608011904.PAA24306@bronze.lcs.mit.edu>, cz@bronze.lcs.mit.edu (Christopher R.

The DECmate II has, in addition to the PDP-8 for executing user code, an 8051 for the floppies, an 8051 for the hard disk, and 8051 in the keyboard.

Is it possible to fit a HD, upgrade memory etc..??? For more specific info, post to alt.sys.pdp8. Other than for a few specific options, DECmates are not upgradable in the sense that you usually reference: DECmate {no designator} means what is now referred in retrospect as DECmate I. The system is 32K, and is the 6120 micro implementation of the venerable PDP-8 where 32K is the normal limit for all of the usual software. Just enough of the alternate control memory of 32K is also implemented to handle the peripherals, but only to the extent of implementing overall control/status, and booting options, and a built-in terminal emulator only if the comm board is present. Thus, the only options are whether there are one or two pairs of RX01/02 (I don't think it was sold with less than RX02, but it can take RX01 or a pair of 01 and a pair of 02 or two pairs 02), the DP278{A or B, where B supports bit-stuffing protocols and is an upgrade later for A} dual comm board, and the RL-278 disk controller for 1-4 RL02's which of course puts this VT-100-like box next to a very large cabinet or two. A printer port is built-in DECmate II is by far the most flexible of the family, and consists of a repackaged machine which is the same overall case as the PRO-325 and Rainbow. Internally an RX50 is an option technically, but is always present. Options include an additional pair of RX50, the RX78 external RX01/02 board {which can control one or two pairs of mixed RX01 or RX02 drives, neither of which can be booted to directly, and are programmed in a slightly incompatible manner to all previous designs which were totally compatible with each other!}, a graphics board, possibly with the VR-241 DEC color monitor {yes, a second monitor; there is no official one-color-monitor version, but the graphics can be directed at the non-optional VR-201 mono monitor}, and a HD controller which can connect one MFM hard disk. {Note that the hard disk controller precludes the RX78 option entirely, and usually the hard disk itself is mounted within the case which precludes the second floppy pair. While in theory you could cable up an external hard disk, thus allowing a second RX50 pair at the same time, some of the software cannot be configured to support the second RX50 pair and HD at the same time.} The HD size can be up to a formatted 64 MB since all DEC HD controllers of this vintage reserve dedicated alternate sectors at the beginning of the disk (which is required to be error-free in that area) and each track has 16 sectors of 512 bytes, a maximum of 8 (not 16!) heads. There is some debate over whether disks beyond 1024 cylinders are supported, but in any case they are rare in the industry anyway. (For example, I use an ST-4096 which is 1024 cylinders, but actually has 9 heads, one of which is wasted, but the 1024 cylinders are otherwise totally used.) There was a case upgrade for all of these machines so that larger hard disks wouldn't overburden the power supply due to the large start-up current of many hard disks, so you can't just drop in a hard disk without checking the power supply ECO! The only other option for the DECmate II is a CPU and memory board that adds either a Z80 and 64K or a Z80, 8086, and 256K {or alternatively 512K, not an upgrade, an alternate board!} where the Z80 can access 64K of the memory only. The 6120 is only indirectly interfaced to this board, and the usual software environment is that the 6120 runs as a server for whatever is running in the APU or XPU board itself when they are active. The only exception is that a portion of DEC's WPS software actually is run in the Z80 while the 6120 waits for the results (DECspell, footnote formatting). All other software runs without the optional CPU and memory boards in 32K only, however the control-panel memory is totally implemented to 32K. However, virtually all of it is dedicated to functions associated with the built-in terminal emulator, etc. The software environment on a DECmate II disk is such that each application owns its own volume or volumes, and can be sub-booted from Master Menu. This is necessary due to the myriad number of O/S'es that can run on the machine which can have up to three CPU's. {Some applications can be called up as separate bootable entities, but most of these are actually bootable OS/278 systems that are dedicated to running a specific application program. In theory, it's possible to revamp them into manually invocable utilities called up from one copy of OS/278, but this isn't what's done normally. In fact, Master Menu itself is one of these! However, there are legitimately several families of O/S for the machine that are distinct, and Master Menu can accommodate all of them, such as WPS, COS, CP/M-80, MS-DOS, OS/278, etc.} The DECmate III is a reworked smaller version of the DECmate II which can only have one pair of RX50 and no hard disk. The only options are a reworked APU board with a Z80 and 64K, and a graphics board. This system must have one monitor but it could be a VR-241 color monitor as well as the standard VR-201 mono monitor. All systems from the DECmate II up use the LK-201 keyboard, usually sold with the WPS keycaps, which in turn implies the blue color scheme for the keyboard as opposed to the more likely red, etc. In theory, there is also an obscure modem option whereby some specially adapted DEC "scholar" modem of the era can be plugged into a dedicated connector on the motherboard. I've never heard of anyone ever seeing the actual board, but it's known that it would be compatible with an appropriate DF modem that was 300 baud and 1200 baud only. Some newer DECmate III cases even lack the little slide-out case section where the modem's modular phone connector would poke through, or even the little telephone symbol that is used to label the connector. Early cases come with a 78W power supply, but newer ones are rated at 150W. In a startling display of retro-engineering, this system uses mono-voltage power supplies, which means that, including the DECmate III+ supplies, DEC bothered to reinvent so many wheels that there are at least six different power supplies to be found in this box! The DECmate III+ superficially looks like a DECmate III, but is quite different inside. The main board now sports an optional hard disk controller on an plug-in daughter board, indicating the likelihood that the system was designed to be a replacement of sorts for the original DECmate III board, but in fact it was never marketed that way. This hard disk controller is compatible with the one from the DECmate II, but due to case restrictions, mounting an internal hard disk requires it to be half-height; only the ST-225 20 MB disk was ever sold with it. The built-in modem connection of the DECmate III is still present, but they don't even implement the chips to drive the connector! The floppy support has been revamped to use RX33 (TEAC HD) drives, but only mimicking the RX50 at 300 RPM. It should be noted that the DECmate III+ can only use RX33, and the DECmate II and DECmate III can only use RX50, since the earlier machines require device-ready drives, and the DECmate III+ requires device-change drives. (Although the TEAC drives can be strapped to signal ready instead of change, they are not seek-ganged as is the RX50!) The DECmate III+ supports two RX33 drives, but due to case limitations, they were marketed with only one drive bolted onto the ST-225 HD. It appears that a contingency plan could have been to sell revamped DECmate III units by deleting the hard disk controller daughter board and adding a second RX33, but this configuration was never sold. The same two APU and graphics option boards of the DECmate III can also be used in the DECmate III+ however, CP/M-80 will have problems getting implemented, since it relies on the present of the second floppy drive, even when getting installed. (To install CP/M-80 on the machine, you have to at least temporarily hook up an additional floppy drive. To do this requires an alternate floppy cable, although the wiring is totally straight-forward and industry compatible. Note that an IBM-PC or PC-clone is *not* a straight-through cable and cannot be used!) There is rumor that there was some form of XPU board for the DECmate III and DECmate III+, possibly with more than the 8086 w/256K or 512K of the DECmate II XPU, rumored to contain an 80286, but none have surfaced, and it certainly wasn't sold. It is known that the RX33 floppy implementation is slightly deficient, in that the RX50 versions are capable of reading-*only* one-sided IBM-PC 40-track disks, while the RX33 cannot. Thus, it's not possible to write a utility to convert from IBM-PC 160K or 180K diskettes. On the DECmate II with XPU, this is a standard feature of MS-DOS to read one-sided IBM diskettes, etc. DECmate III+ comes with a 160W power supply. The only seeming difference is that there is an additional 4-prong power connector ganged into the power wiring, as opposed to potentially different innards from the DECmate III supply. As in the DECmate III boxes, the supplies come in 110V and 220V variants, instead of a switchable version as most equipment usually is constructed. cjl \/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/ Newsgroups: comp.terminals Path: utkcs2!stc06.ctd.ornl.gov!news.er.usgs.gov!mcmcnews.er.usgs.gov !news.indiana.edu!vixen.cso.uiuc.edu!howland.erols.net !news.maxwell.syr.edu!news.new-york.net!watsun.cc.columbia.edu!jaltman Date: 26 May 1997 16:09:37 GMT Organization: Columbia University Message-ID: <5mcck1$hqg$1@newsmaster.cc.columbia.edu> References: <338A1F66.5AD8@slb.admin.ch> From: jaltman@watsun.cc.columbia.edu (Jeffrey Altman) Subject: Re: win95/NT LAT Stack MARCEL AMORE wrote: : Hi : : I am looking for a low cost or a freeware LAT protocol stack for Win95 or NT. : : Any informations about a product ? : : Best regards, Martchy There are no free LAT stacks for Windows.

I can't give you a definitive answer without an IC number, but it could be the DUART. On the basis of my investigations into the VT320 board I've got, I think that the microcontroller uses its serial port to drive the keyboard link rather than the comms ports. On the VT320 the device is a Motorola MC2681. The ROM may well have a number starting with 53xxx.

Clearpoint wants something like $149/4Mb, and when we told our DEC salesman that unless he could meet that price, we'd be forced to buy extra memory from them, he met the price. Dec wants ~$500/4Mb!!! Be warned that unless you are running InfoServers, you will need 10-12Mb before the VXT2000 can load its boot image.

Not sure, but we have 2 VT1300's and two VXT2000's (all color). The VXT2000 is more versatile, since it can log into any machine on the net (that is running xdm), not just a fixed machine running a prompter process. The VXT2000 can also establish a telnet session in its own window, if you don't want to start a full Xsession. (With version 1.1 of the VXT software, you can supposedly do all these things from a VT1300, but only if running them from an InfoServer--a separate box that handles a lot of the xterm load. We don't have these, so I can't vouch for how well this works.) As far as speed goes, the VT1300's, VXT2000's, and the system console _seem_ equally fast. The VXT2000 can also look up hosts from your nameserver, something the VT series can't do (at least as far as I can see). > - How does a VXT2000 Color compare to let's say NCD17c and NCD17cr or > comparable Tektronix X terminals?

We got the Ultrix version of the software when we got the first VXT2000, but when the update to version 1.1 was shipped, they sent us the VMS version. Really brilliant, since we have no VMS machines running X on campus, and this department has NEVER had a VMS machine. This isn't the first time either. The only tape that we ever got from DEC of software for the VT1300's was for, you guessed it, VMS.

What you could do is treat the device on Comm2 as a printer; go into the GLOBAL settings of the terminal, and make sure that middle box says S1=Comm1. Then go into the Printer setup screen, and setup the port characteristics so that it can talk to your device. You can go three ways from here: [1] * Dump the ENTIRE screen to the device. Do this by hitting the 'Print' key. * Get the host (on Comm1) to download the information through your terminal. Information sent will not show on the VT's screen. To turn on printer controller mode, the host should send: CSI 5 i to turn off: CSI 4 i Alternatively, you can just go into Printer Setup again, and change from Normal Print Mode to Controller Mode. Note that this is one-way communication; if you want the host to see what the device is responding with (if at all), make sure that you have 'Printer To Host' selected in the printer setup screen. * To print a selected number of lines, make the host send the following to your terminal: Tell the terminal the region to print: CSI topline ; bottomline r e.g., to select lines 5 to 10: ^[[5;10r Tell the terminal to print only the things that are in that region: CSI ? 19 l Tell the terminal to print it: CSI 0 i Personally, I'd go for the second option. No fiddling about with the terminal settings each time you want to download stuff, and the host does all the work for you! Good luck! Simon. -- Simon Coombs.

Part numbers for the manuals, details of the graphics option and Setup B screen are available in the Terminals and Printers Handbook 1983-84, which is online at: http://vt100.net/docs/tp83/ Chapters 5, 6 and 7 deal with the VT100 family. > I tried to find this info for over 2 weeks, on Webcrawler, > Infoseeek, Lycos, Altavista, Lycos (ftp search), Ask Jeeves, hotbot and > what I have gotten is very sketchy at best.

Joe we are talking about an old vector-drawing CRT, not the terminal type device. http://www.spies.com/~aek/pdf/dec/pdp6/F-65_PDP-6_Handbook_Aug64.pdf and tony, Both displays had 1024/10240 x/y and a multi level intensity control. The screen is round but the vectors you drew were a square. There was a diagnostic to align the display where you draw a box 1024 by 1024 at the outside edge and an X from corner to corner to set up a rectangular display. God, I miss vector scopes! The box must be almost the same as the PDP-6/346 display; I don't think DEC changed much in the way of controls, as I look at my binary IOwords for the 340, all the bits seem to fall into place. The interrupt system seems the same, too. You can get interrupts for the light pen, or if you try to draw out of the 1024 boundry. Maybe someone will make a Java simulator and we could play with it in virtual space. I don't think holding the mouse up to the screen and pushing a button would feel the same!!! ////////////////////////////////////////////////////////////////////////////// Newsgroups: alt.folklore.computers, comp.sys.dec References: Message-ID: Organization: Spies In the Wire Date: Thu, 18 Dec 2003 20:20:46 -0800 (PST) From: Al Kossow Subject: Re: PDP-8...did it have a CRT display?

For quite some time, the "DEC Terminals" page at that URL has contained the following text: "The next generation consisted of the VT320, VT330, and VT340, while a further generation comprised the VT420 and VT440." Today I have changed it to omit the reference to the VT440 and have put a small note to correct the false impression. Among my collected terminal documents is one prepared by DEC as an internal specification of the VT510 model, which consists largely of a kind of checklist of DEC terminal models and features implemented in each one. Encoded in Postscript, this file resides here: http://www.cs.utk.edu/~shuford/terminal/dec_term_function_checklist.ps While it contains entries for many DEC terminal types, including VT100, VT220, VT320, VT340, VT420, and the VT510, it contains no reference to anything called "VT440". An educated guess on what happened: it is likely that, when the VT420 was being specified and positioned to replace the text-only VT320, DEC decided that the design effort necessary to make a replacement for the graphics-capable VT340 was too great, given the market projections for sales of this hypothetical "VT440". So the existing VT340 model was retained in the catalog and sold alongside the VT420 until the VT525 took over as the graphics product. Peter Sichel might know the whole story, but he doesn't seem to read this newsgroup much anymore. (The VT330 was an interesting beast: if I recall correctly, it could display only text, but it could connect to two separate sessions at the same time, displaying one on the top of the screen and one on the bottom. There were two serial ports, but the device could also obey the patented "Terminal Device Session Management Protocol" to multiplex two sessions on one wire. Apparently the VT420 also implemented TDSMP, but the control sequences never appeared in the product documentation.) [OK... writing without referring to the above information in this file, I forgot that the VT330 could do black-and-white graphics. ...RSS] As to terminal emulators that can do graphics: I have never seen a freely available package capable of ReGIS. A few of the commercial products can/could do it, such as WRQ Reflection, SmarTerm 340, Rumba, DCS EM340, poly-STAR/GW, and KEAterm: http://www.cs.utk.edu/~shuford/terminal/regis_emulators_news.txt The old MS-DOS Kermit by Joe Doupnik can do the more bit-map-like Sixel graphics, but (to my knowledge) Kermit-95 cannot.
