I seem to remember seeing an add-in board which would add PC style serial
ports to Macs. Now this was several years ago; it was for the NuBus; and
it was rather expensive. I believe it was done so you could interface lab
equipment to Macs. It may have even been sold as a Labview add-on. I'll
check with my local Mac guru. He's done all sorts of wacky (sort
of) things with his Mac (controlling servo motors, real-time data
collection, etc).
Now theoretically, it should be possible to pop a PCI serial port card
into a Mac, hack out or buy a driver, and then use the interface on the
new card. Doesn't really help the people who have iMacs though. Another
possible avenue is a USB to serial convertor (if they exist). I know that
USB -> parallel adapters exist for the PC side, but as I'm using Windows
NT (doesn't yet support USB), I haven't really looked into exploiting the
capabilities of USB.
