The signals of the GE863-QUAD/PY serial port are:

RS232	Signal	GE863-	Name	Usage
Pin		QUAD/PY
Number		Pad Number
1	DCD -	42	Data Carrier Detect	Output from the GE863-QUAD/PY that
	dcd_uar			indicates the carrier presence
	t
2	RXD -	38	Transmit line *see Note	Output transmit line of GE863-QUAD/PY
	tx_uart			UART
3	TXD -	37	Receive line *see Note	Input receive of the GE863-QUAD/PY
	rx_uart			UART
4	DTR -	39	Data Terminal	Input to the GE863-QUAD/PY that
	dtr_uart		Ready	controls the DTE READY condition
5	GND	8-17-28-36-	Ground	ground
		45-48-50-56
6	DSR -	43	Data Set Ready	Output from the GE863-QUAD/PY that
	dsr_uart			indicates the module is ready
7	RTS -	40	Request to Send	Input to the GE863-QUAD/PY that
	rts_uart			controls the Hardware flow control
8	CTS -	41	Clear to Send	Output from the GE863-QUAD/PY that
	cts_uart			controls the Hardware flow control
9	RI -	44	Ring Indicator	Output from the GE863-QUAD/PY that
	ri_uart			indicates the incoming call condition

NOTE: According to V.24, RX/TX signal names are referred to the application side,

therefore on the GE863-QUAD/PY side these signal are on the opposite direction: TXD on the application side will be connected to the receive line (here named TXD/ rx_uart ) of the GE863-QUAD/PY serial port and viceversa for RX.

TIP: For a minimum implementation, only the TXD and RXD lines can be connected, the other lines can be left open provided a software flow control is implemented.

The signals in the UART connector on the EVK are:

DCD	RXD
TXD	DTR
GND	DSR
RTS	CTS
RI	GND
