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.
