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?

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.

What does $set term/inquire do in your case? (use $show term/all later
and/or try editing after doing it)
sylogin.com runs it on some terminal types and not others. This may be why
the console works and other forms of login don't. If that's the case you
can edit sylogin.com to include those additional login sources in the
inequity processing (in later versions of VMS it's the TT_NOINQUIR variable
you need to change the settings for - I don't have a 5.3 machine up to
check so it may be slightly different).

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 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.

I believe set term/inquire does more than set term/type. Did you give it a
try? You may also want to put TCP/IP on your MV if you can, and save the Pi
middle man and see if makes a difference.

There are several editors in VMS.
You might try one if the others.
I think edit/Tpu is one. Can’t remember the others.
Maybe someone on the list can.

Might be worth trying SET TERM/DEV=VT105 on the VAX, this works much better for TPU for
example than VT100.

There’s probably a shell script floating around that does a good job of making the
keyboard work correctly when using an xterm. I think it’s called vt100.sh. Though the
last time I tried to use it was on a Mac and the xterm wasn’t compiled with the necessary
options.
These days I use SecureCRT.
