[comp.sys.ibm.pc] IBM PC Terminal emulator / Graphics interface

car@pte.UUCP (Chris Rende) (07/29/88)

We have IBM PC compatibles which we use with our Unix System V release 2
system. We would like to find a terminal emulator package for the IBM PC
which can work nicely with VI, curses, etc... The other important feature
we need is for the emulator to display graphics from Unix programs. Perhaps
a Tektronix emulator of sorts. (This may require 2 different emulators, one
for use as a terminal, the other as a graphics display).

Any information or experiences on products or source code would be greatly
appreciated.

I suggest you look into the public-domain Kermit program(s) out of Columbia
University (and widely available just about everywhere else).  The current (?)
version appears to be v2.30, and performs VT102 (NOT VT100; my major com-
plaint) and TEK 4010 emulation.  If you can create a VT102 termcap you should
be all set; personally I find that using the "standard" VT100 termcap with
v2.30 is a royal pain, and I prefer slightly EARLIER (v2.28 or before) versions
as they do the *best* VT100 emulation I've seen.  They DON'T do graphics, how-
ever.  

But what the heck, it seems to be FREE, at least no one has ever asked me to
pay for copies, in a University environment where such things are taken IN-
CREDIBLY seriously.

Good luck!

I do have vt102 termcap and terminfo entries that work with both Kermit-MS
v2.30 and my vt220 in vt102 mode.  They even work on my UNIX-PC.  If you want
them I'll mail them to you.  I also have entries for my CP/M Kaypro, if anyone
is interested.

I find it hard to believe that the VT100 emulation has deteriorated in the
newer versions.  How about some specific examples, Chris ?  

Why would you have a complaint about VT102 emulation ?  Isn't VT102 a superset
of VT100, with the added features of printer control ?  I haven't had any
problems using a VT100 termcap with Kermit 2.31 or 2.30 for that matter.
Perhaps, your termcap isn't standard or complete ?  Again, I'd really like to
know just what VT100 feature has been dropped in going to the later versions.

BTW, this is not intended to be a flame, just a loyal Kermit supporter who's
curious.

It is freeware, subject only to a small media charge.  It is also currently
being issued on the .bin board.  Works real well too.

Yes, I can confirm that - NOW; it's being sent from the very site at which I 
am located.  I posted my original message about v2.30 early last  evening, then
later last night a friend here told me that our system administrator had 
received, and was posting to the Net in 9 parts (spaced eight hours apart),
v2.31.  The timing on this just wasn't what it should have been, I guess.

2.31 is out; it adds a great script language and some other improvements.

Don't complain. VT102 is a strict superset of VT100; the difference is
that VT102 allows inserting and deleting characters in the middle of
the line, which  makes editors much easier to use at slow speeds.

Use the "standard" vt200 termcap, which will allow enlightened
programs to use the insert/delete character feature. I use kermit 2.31
with a vt200 termcap and emacs works perfectly. (emacs seems to know
all about vt200's). Anyhow I don't know of anything VT200 supports
that VT102 doesn't; maybe some arcane things like double-height
half-letters and stuff but nobody uses those.

Thats weird. 2.28 didn't do VT100, only VT52 and Heath-19. I guess
this goes to show that kermit is such a good program that its VT52
emulation beats other VT100 emulations :-) (But seriously, VT52 lacks
highlighting, a serious limitation).

You can get it by ftping to cu20b.columbia.edu; write to me if you
can't figure out how to do this.

No flame taken..

If Chris want's to argue, that's fine with me.  I too am a loyal KERMIT user
and Chris and I talked about this at some length the other night.

I have had no problems with our termcaps and kermit on either of our systems,
(VAX and Unix) but I don't use all of our editors/programs available, while 
Chris does.  So if Chris said he found a problem, chances are it was real!

If the NEW kermit hasn't corrected the problems, then I PERSONALLY think that
the KERMIT 'development team' should listen to Chris!

My experiences with vt102 emulation (on an QuadHPG in EGA mode) is that kermit
sometimes switches into 43 line mode. (Thanks fine with me.)  All attempts to
clear the screen while in 43 line mode fail.

Since I connect to a 4.2BSD unix machine, I assume that my termcap is correct.
Perhaps you could email/post a correct termcap to me/comp.sources.misc.

>...just a loyal Kermit supporter...
Me too.

One thing that happened with the newer versions was a bug fix relating to
highlighting and change of intensity.  The older versions were nice and
bright when you came out of reverse video.  The newer ones correctly (but
alas not as pleasing) go to "normal" video, which is rather dim. Hope this
helps...

The VT102 termcap is nothing but a VT100 termcap with two new cursor motion
commands (for speed) added.  So, if it supports VT102, it supports VT100.
By termcap, I also mean emulation.  The reverse is true, ie, if you have a
terminal emulator that supports only VT100 and it gets one of the two VT102
cursor commands, you will have problems.

On my vax (4.3BSD) I was using the VT102 emulator as VT100 termcap, until
I fixed up the VT102 termcap entry, which was the VT100 with the two added
cursor commands.
