I'm assuming you already have one serial port - I've seen a project
online where a guy converted an old unneeded pcmcia modem into a serial
card for his sony vaio, which had no ports at all.

Lots of old card modems lying around now I reckon... could be an
interesting project!

When somebody suggested few had ever been interested in a PCMIA serial
port, my reaction was that likely people did add things that bypassed
the need for a serial port. Your suggestion reinforces that, since likely
people would be more interested in adding a modem than just a serial port.

On the other hand, it may be that the vintage is too late. Ten years ago,
I took an ISA 2400Baud modem and yanked the UART, adding some line drivers
and receivers so I had a 2400 Baud serial modem to use with my Mac.

I would have duplicated the process with a faster modem later, but by
then there was no standalone UART. It was part of some LSI IC, and there
was no way of accessing the needed points.
