[1] does CP/M abstract serial hardware into a set of
common calls, or is
that outside its scope?
Not really. Often, on more recent CP/M machines, the PUN: and RDR@:
drvies were mapped to a serial port, but the funcitonality provided was
not enough for a serious terminal emulator. In genral CP/M comms progrmas
had to me modified for each particualr machine.
Was Kermit ever ported ot the QX10? I would be suprised if not. And most
microcomptuer kermits act as a terminal emulator too.
