Hi Folks,
Here's the summary of what I found out about a vt[12]00 emulation under
OpenWindows 2.0. Sorry for the delay in summarising, little things like
starting a user service kept cropping up :-)
The problem was....

The main problem is with the type-4 keyboards (SLC's & co) which
emulate a PC keyboard (argh..) and combine the cursor/keypad in one
area. So Keypad 4 is also cursor left, keypad 6 is cursor right, etc
and you get these cursor actions when you want a keypad action.
The solutions: (subtitled "This is as good as it gets...")
0) get rid of the VAXen
Actually I kinda liked this one but the Boss didn't... :-]
1) use one of the current SunView VT emulators under OW.
I tried crttool from the rice archives, which unfortunately still
gets the cursor keys/keypad confused i.e. keypad 8 is up arrow, not
KP8 (sigh) otherwise this would be an acceptable solution. Also in
the running was te100tool from Sun themselves which does get the
keypad _exactly_ right (if you've got the patched version..:-) but
this costs money so and we couldn't afford to install it on all our
workstations.
2) Modify the keymap for xterm.
This is probably the best thing to do, even though it's not perfect.
I received a couple of keymap definitions (at the end of the
article) which make life easier (if not perfect). In the course of
my investigations the Sun hotline support informed me that xterm "is
not a supported product." This kinda worries me...
3) use a OpenWindows/X11 client which emulates a vt100
I received a beta-test copy of xvttool which provides vt100
emulation and keypad emulation using on-screen buttons. This works
quite well as long as you're comfortable with _lots_ of mouse work.
Contact the author, Bruce Barnett <barnett@unclejack.crd.ge.com> for
more info.
I received a pointer to mterm, available from 132.206.1.1 in
directory X/mterm.src. I retrieved it, but couldn't get it to work
(X Error: BadAccess). This looks to do what I want but I don't have
the time nor the knowledge to fix it.
In conclusion, I get along with the xterm keymap translations and I'll recommend that to our users.
