I designed a state-machine based application that handled 3 serial ports
(mutli-port serial card sharing on interrupt) simultaneously downloading
data files at up to 19.2Kbps per channel.
I also designed a system that used 2 standard COM ports simultaneously:
one for remote access and one for transferring data. Worked fine at up to
19.2Kbps (the fastest cheap modems of the day, e.g. USR Sportsters).
Under MS-DOS 6.22.
So I have no idea what you're talking about really :/
