Bradley,
Not sure what you mean by "accessing the serial port"
here. Under Linux (and Unix for that matter), it is
just another file. Once the port has been setup,
(Baud, stop bits, parity, etc.) via either stty
before starting the program, or ioctl's in the
program after you open it, "/dev/ttyS0" or whatever
depending on which port you are using, you can just
read from it, and capture whatever data is being sent.
I don't think it is much more complicated than that.
If I have missed something or you need more help, let
me know. There are a few other developers on the list
as well...
