Can you set your terminal emulator to emulate a vt220 instead of trying 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.

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?
