	 * NOTE: The wiring we assume is the one on the 3min:
	 *
	 *	out	A-TxD	-->	TxD	keybd or mouse
	 *	in	A-RxD	-->	RxD	keybd or mouse
	 *	out	A-DTR~	-->	DTR	comm
	 *	out	A-RTS~	-->	RTS	comm
	 *	in	A-CTS~	-->	SI	comm
	 *	in	A-DCD~	-->	RI	comm
	 *	in	A-SYNCH~-->	DSR	comm
	 *	out	B-TxD	-->	TxD	comm
	 *	in	B-RxD	-->	RxD	comm
	 *	in	B-RxC	-->	TRxCB	comm
	 *	in	B-TxC	-->	RTxCB	comm
	 *	out	B-RTS~	-->	SS	comm
	 *	in	B-CTS~	-->	CTS	comm
