I'm thinking about the following situation - 1 system acting like a

machine on sio0, using null modem cables.
Along with milti-io serial cards we use multi-usb serial
converters, such as SUNIX UTS7009P (7 USB to serial adapter):

I need to look it up when I'm in front of a real computer, but there
are a number of reasonably priced multport USB to serial converters
out there. We have a 16 port model that's rack mounted and cost
around $400. It works better many of the more expensive multiport
serial cards. Paired with conserver, it's a really nice solution.
Conserver's logging is great...
I've used old dedicated terminal servers in the past and they can be a
pain to deal with. The newer ones are probably nicer, but are also
lots of money.
