Hello to all DOS program collectors / authors.
Can you supply a simple machine code routine to do serial I/O
from a PC at TTL level from a parallel port without a UART in
hardware - a software UART is the essential requirement.
It would suit my purpose if there were two routines that can
be called from say Q-BASIC to allow TTL ASCII transfers such
as to a radio without RS-232c level signalling.
A baudrate range including 4800 is needed.
I do not know how to tell Google all that, so I think Packet
is an excellent place to start looking for clues.
