	The emphasis is on the word DONGLE above. I just spoke with an
	old friend and there is a circuit board that is housed in one
	end of the cable that has misc. micro electronic parts on it. This
	could be RS232<->???? converters or some sort of dongle thing. In
	other words, it's more than just pin x to pin y sort of thing
	for the Smart UPS from APC.
