Pasteler0 wanted to build an external control system for Winamp. Using the COM-port plugin he was able to wire up 4 control buttons directly to his serial port. The software also supports a 15 button mode. The switches are mounted in a clear plastic floppy disk box and connected to the computer serial port using CAT5. It’s a nice hardwired solution for control, but if you want just a simple remote, try WinLIRC.
