I do this sort of thing all the time, and there are lots of approaches. Check out "expect", which aims to automate interactive things. I'm using perl's Expect module for this, and either cu or nc (netcat) to handle the serial port itself. Expect (either flavor) wraps itself around some process, then allows you (your script) to send stuff to the session and to "expect" certain things from it, fixed strings or regular expressions, and to take actions depending on the result.
