I was just reading the manual at a store, so the following may be off.). They don't seem to actually send any data either way--they just use a couple of lines as on/off signals (probably the modem control signals?). E.g., when you lose power, one of the lines changes from high to low, and the computer can shut off the computer by pulling one of the other lines low (or something like that). --Tim Smith
