I have tried that. It seems VT220 isn't valid in VMS 5.3-1, but VT200 is
and I have tried it as well as most of the other types as well.
EDT is very limited in what it supports though:
SET
TERMINAL
Format: SET TERMINAL { HCPY | VT100 | VT52 }
{ SCROLL | NOSCROLL }
{ EDIT | NOEDIT }
{ EIGHTBIT | NOEIGHTBIT }
Since it works under RSX11M and M+ I was expecting it to work under VMS as
well, but clearly not. I am wondering if it has something
to do with ssh from my laptop to the pi. I have made sure TERM in each
shell has been set before I ssh and then before I dnlogin, but
that hasn't helped either. I don't have a screen and keyboard on the pi. I
may need to setup the decnet stuff on one of my other Linux
machines and try eliminating ssh. And I realize the subject says telnet,
but it really is more ssh and then dnlogin.

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?
