I wish it was as simple as Interrupt 14H.  The bitter truth is
that what should be the simple act of receiving serial data on a P.C.,
is a nightmare.  Interrupt 14H which is what the bioscom function is based
on will only work as expected on P.C.'s with an IBM-compatible BIOS.

        On other systems, it just doesn't work.  One is almost forced to write
an assembler routine that talks directly with the port.  The Int 14H and
the bioscom function don't even set up interrupt vectors so one is forced
to use lower speeds to keep from missing data.
