That's going to be very difficult, I'm not even sure it's possible.

For C, a book called "Advanced Programming in the Unix Environment" by
Stevens.  Good book, he has a few more books that are similar, including some
good ones on TCP/IP.

I haven't done anything like this in perl yet, but I know there are a few
modules on www.cpan.org dealing with serial ports.

Excellent program called minicom.
