It depends what speed you want to talk and what you want to do. Firstly
you can't do IrDA and serial at the same time on a PC110 - there are two
UARTS and one is part of the modem chip, the other switchable.
As to parallel port serial, at 1200 baud its merely a right pain in the
backside. I'd be inclined to build something a bit more substantial with
proper buffers as well as the required voltage shifters. Perhaps a PIC and
a MAX232 with some of the PIC I/O lines wired to be the parallel port link.
At that point writing a serial driver for the PIC over parallel isnt very

will be getting an official US/EU product version and launch later this
year according to one computer magazine.
