The Arnet "Smart" cards had on-card microprocessor and buffering for better
throughput and lower main cpu utilization. The other "non-smart" cards were
more like a plain old serial card on a PC, differing mostly in that they had
more than 2 ports.

I have a 4-port Arnet card (non-smart) that has a (large) ISA card, a ribbon
cable, and an external mounting plate with a "breakout box" (built for a max
of 8 ports), with 4 connectors loaded. I used it with SCO UNIX and it worked
fine, actually better than the SCO UNIX did :-) It is very difficult to
develop C code with a compiler that dumps core every time I try to generate
a listing file...(dang M$ compiler!).

Digi DID acquire Arnet some time back. Last time I looked, Digi still had
some drivers and documentation for the Arnet stuff on their web site.
