Most (all?) CE devices come with both an IrDA port and a serial port
typically used for PC synchronization. Why wouldn't you just attach to the
existing serial port?

rajackson@qnx.com once suggested this solution:
"Since IRDA can operate as a simple serial device. It would be simple
to build a IRDA to RS-232 converter (it will need a IR led and Photo
diode and some level shifters). The you could plug the RCX tower into
the converter and the CE device could then signal the tower using it's
IRDA port."
I wonder if anyone has tried this?
