Also, anything on a DS200MC terminal server?
Assuming you mean a DECserver 200/MC, I was using these in 1988, so
I'd guess that they're acceptable for discussion on this list, or will
be soon enough.
As you wrote, it's a terminal server. Eight RS-232 ports with enough
modem control to support most asynchronous communications needs, and
an Ethernet port for connection to your LAN. As I recall there is
enough firmware in the thing to request an executable image via DEC's
MOP protocol, pick one responding host to download it from, and once
that image is downloaded (via MOP) and running, to do terminal and
printer service via DEC's LAT protocol. They do not do TCP/IP-suite
protocols, though later models of DECserver may.
Hence you can plug terminals, modems, printers, or computers into the
RS-232 ports, and set them up so that either they connect to other
computers via LAT, or so that other computers (or other terminal
server ports) can connect via LAT to "services" associated with the ports.
Generally speaking, they're not real useful outside DEC environments,
but are very useful there.
