	61	CTS2	CLEAR TO SEND (serial port 2) - CTS is a
			function supplied to the terminal by the modem,
			and indicates that it is permissible to begin
			transmission of a message. When using a
			modem, CTS follows the off-to-on transition of
			RTS after a time delay.

	62	RTS2	REQUEST TO SEND (serial port 2) - RTS is
			supplied by the terminal to the modem when it
			is required to transmit a message. With RTS off,
			the modem carrier remains off. When RTS is
			turned on, the modem immediately turns on the
			carrier.

	63	DCD2	DATA CARRIER DETECT (serial port 2) - sent
			by the modem to the terminal to indicate that a
			valid carrier is being received.

	64	DTR2	DATA TERMINAL READY (serial port 2) - a
			signal from the terminal to the modem
			indicating that the terminal is ready to send or
			receive data.
