I'm going to go at it from the other direction, I am writing an IDE
(32 bit windows) for the pbFORTH system. My intention is to send a
keepalive character every now and then to stop the tower going to
sleep, at the moment I am debugging FORTH words by emitting strings
back to the PC, but after a while the tower doesn't see them even
though the RCX is still spewing debug messages. It would have been a
good idea if the tower had been designed to look at the traffic in
both directions before deciding to timeout.

(...) Usually a capacitor lives across the power lines, and introducing a wire would be a good way of drianing the battery, burning the wire and possibly yourself!!! DON'T DO THIS...
