Well, only RS485 and RS422 afaik allow multiple nodes so could be called a network. RS232 is point to point and short distance only

Even point to point, in some settings RS422 is better because the differential signal allows longer cables.

A serial card. Be careful though, many standard serial cards don't allow speed above 115k2.
