Table 3-12. Connector P2, J11 Interconnect Signals (MVME712x) (Continued)

	Pin Number		Signal	Signal Name and Description
			Signal
	P2	J11	Mnemonic
			Mnemonic



	A23	46	RXD4	RECEIVE DATA (serial port 4) - data that is
				demodulated from the receive line is presented to the
				terminal by the modem.

	C24	47	GND	GROUND

	A24	48	RTS4	REQUEST TO SEND (serial port 4) - 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.

	C25	49	GND	GROUND

	A25	50		Not used.

	C26	51	DTR4	DATA TERMINAL READY (serial port 4) - a signal
				from the terminal to the modem indicating that the
				terminal is ready to send or receive data.

	A26	52	CTS4	CLEAR TO SEND (serial port 4) - 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.

	C27	53	GND	GROUND

	A27	54	DCD4	DATA CARRIER DETECT (serial port 4) - sent by the
				modem to the terminal to indicate that a valid carrier
				is being received.

	C28	55	GND	GROUND

	A28	56		Not used.

	C29	57	GND	GROUND

	A29	58	TXD2	TRANSMIT DATA (serial port 2) - data to be
				transmitted is furnished on this line to the modem
				from the terminal.

	C30	59	GND	GROUND

	A30	60	RXD2	RECEIVE DATA (serial port 2) - data that is
				demodulated from the receive line is presented to the
				terminal by the modem.
