Paul,

For relays, power sense, and 232, might be possible. However, for IR data, not likely.

But, if you need IR and know you will have to convert the Pronto IR Code data to some other format, why not just invest in a Global Cache GC-100 12 which gives you serial ports, relays, and 6 IR ports? Plus, with this configuration, you get true asynchronous 232 as the serial ports communication done using TCP/IP.
