Those devices are generally only switchers, that is, only one device can be
active at a time. Some are manual and some are automatic. Now that you
mention it, they do seem to have disappeared lately.
There is a NuBus card called, I believe, a Hurdler that will give you up
to, again I believe, 4 additional serial ports. It is frequently used for
BBS systems. I don't know the name of the company that makes it, but I bet
if you called Spider Island (makers of the TeleFinder BBS software) or
SoftArc (who make the FirstClass BBS system) that they could give you
current information.
