As I said, I've never tried this before :) It's probably a
matter of reading (maybe even just using `cat` without
programming) from /dev/cuaaX or whatever device you need
(Device names for serial ports are listed in the FAQ, if I
recall correctly). I know this is vague, but I have never
even messed with the serial port before :) (My modem is
internal, and I have no device connected to the serial
port). I assume that getting ASCII input from the serial
port shouldn't be hard though.
