Can you set your terminal emulator to emulate a vt220

vms to do vt100. You used the set term vt100 command before?
Vms has help. Just type help set from a command prompt.
Also can do show term to see term params. Maybe show term /all … don’t
remember exactly.
Yes. "$ SET TERM/VT100" or "$ SET TERM/VT220" I believe will do the
right
thing depending on your terminal emulator. SHOW TERM usually is enough,
though /ALL can't hurt.
Beware, though, that EDT really loves to use the keypad keys in extended
mode, and all the 'commands' are GOLD + <something> and you need to be in
that mindset to use it for anything except straight text entering, or using
the arrow keys to find a place to insert/delete text. And it's picky, so
the terminal emulation has to support I think the alternate keypad
encodings (there's three: normal numbers, the normal encoding and
the alternative encoding for some reason that has decayed from my mind
after 30-odd years).

I feel like I have tried everything, although I'm sure I haven't...
I have my real MV 3100 up and running with a serial terminal on the
console
port. It works great but I don't want to sit
by the machine all the time
to
do stuff. I have DECnet running and am able to
connect to it. I have an
old
raspberry pi running a minimal linux setup with
the decnet stuff
installed.
So I ssh to the pi (named gatewy) and from there I use dnlogin to talk
DECnet and connect to the machines. This way I can connect to my PDP-11
machines running RSX11M and M+ and use EDT to edit files in screen mode.
When I try the same under VMS, EDT starts, loads the file and enters
screen
mode but just shows a blank screen with the
cursor in the top-left
corner.
If I go to line mode I can walk through the file
and edit using line
mode.
But as soon as I go back to the screen mode (the
change command) I just
get
the blank screen.
I have made sure TERM in each shell is vt100 and I have tried forcing VMS
to VT100 but it stays with a vt200_series terminal. I also have a SIMH
MV3100 also running VMS 5.3-1 (they both run on that version) and it acts
the same way as the hardware MV3100. If I go onto the console connection
in
SIMH EDT works fine, as on the physical terminal
on the real machine.
Anyone have any pointers or ideas I can try?
