Hi Guys,
Just thought I'd mention in case anyone is interested...
Having recently acquired a couple of VAXen, I've taken the time to
update my LAPTALK terminal program to provide MUCH more complete
VT-100 emulation. This is a very small (<20k) DOS program, so you
can use it to turn any old PC into a terminal.
First the bad news - Like most PC/text based VT-100 emulators, it
DOES NOT support:
- Double width/Double height lines.
- 132 column mode.
- Split RX/TX speeds.
The good news - It does support "most everything else" now. In fact,
it's the only emulator I've tested which passes all of my "VT-100
Checkup" tests (excepting for the limitations mentioned above) - I've
included the test program in the archive.
It also adds a few extra features you might find useful:
- Fairly power script language for automating sessions.
- 40 programmable function keys (F1-F10, ShiftF1-F10, CtrlF1-F10 and
AltF1-F10) with on-screen labels. (very handy!)
- If you have a VGA display it will load a custom character set to
provide the complete VT-100 character set including the graphics
mode characters. I've also include a font editor so that you can
create your own custom character sets if you like.
I've made the package temporarily available at:

If there's any interest, I'll find it a permanent home.
Regards,
Dave

Any possibility that your VT-100 emulator can be extended
to support 132 character text lines? Most of the programs
that I write are in MACRO-11 and they require 132 character
text lines for the list files which are generated. The
alternative is to use 80 character text lines with wrap
around and that is so messy that it becomes almost useless
by comparison.
The other reason is that I use the KEYPAD characters under
RT-11 for both KED and SL:(Single Line Editor). Are you
confident that the <NumLock> keypad key acts as the <GOLD>
key which translates to the 3 character sequence: "<ESC>[P"?
Also, the keypad comma, ".", key on the VT-100 is just above
the <ENTER> keypad key, but does not exist on the PC keypad.
I finally settled on the <Pause> key as a substitute since
there never seemed to be any use other for <Pause>. What
does your VT-100 emulator substitute for the keypad comma,
",", key?
And finally, On the VT-100 keyboard, the SCROLL/NOSCROLL key
is at the bottom left hand corner of the keyboard. While the
standard 105 keyboard from a PC can't exactly correspond to
the VT-100, the <Left Ctrl> key can act in that manner and the
<Caps Lock> key then becomes the <Ctrl> key on the VT-100. Is
your VT-100 emulator able to manage this aspect as well?
Sincerely yours,
Jerome Fine
