I have a simple WIN32 console application (with C source code) that opens the
USB tower to listen for messages from the RCX. You can easily modify this
program (using the WriteFile() API system function) to talk to the RCX.

I have documented the messages that are sent by the Mindstorms IR remote
control, which are probably the same ones used by BricxCC:

I hope this helps. Good luck with your class!
