A couple years ago I built the relay control xbee setup described here http://www.adafruit.com/blog/2009/04/21 ... ol-relays/
Now I'd like to modify it so that I can toggle the state of the remote relay via USB/serial instead of requiring a hardware button press (which I was using a parallel port for before).
But I've banged my head for hours and can't figure out how to either send a remote command, or to get the state of the local USB xbee to pass to the remote.
I'd appreciate any guidance.
