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 :/

Don't be silly. Of course DOS has interrupt
handling. See e.g.

Well I guess you have never used a SERIAL PORT under DOS!
