I bit of googling showed a few people on the SimH mailing list
were thinking about a virtual appliance version. I don't know if
they did it. They were talking about a stripped-down Linux.
So how would we connect a glass terminal or a DECwriter to it?
Simply serial. It should be possible. I've used a vt420 connected via
serial to a h/w port on my PC, to then pass through VirtualBox "into" my
OpenBSD vm. Dunno if SimH already does allow this, but it's open source
:) If it can grab socket or open a file, opening a device file in linux
or bsd shouldn't be that hard.
SIMH allows one to connect a virtual serial line unit to a telnet port.
That's about it - it doesn't connect to a physical serial port. To do
what you want to do, you might need a terminal server. -- Ian
