8692omSF module 133

Connection to TXD and RXD signals and GND is sufficient for the console serial port to fully function. The Console port does not support any inbound flow control; that is, the port does not toggle control lines to indicate an input buffer full condition.

"Pin assignments: 8692omSF module Console port" (page 133) lists the pin assignments for the Console port for both the DTE and DCE settings.

	2	TXD (Output)	RXD (Input)
	3	RXD (Input)	TXD (Output)
	4	DSR (Input)	DTR (Output)
	5	GND	GND
	6	DTR (Output)	DSR (Input)
	7	CTS (Input)	RTS (Output)

Modem serial port

The Modem serial port is implemented on a DB-9 connector wired as a DTE connection.

To set up modem access, you need a DTE-to-DCE cable ( straight or transmit cable) between the Modem port and a modem or terminal server.

"Pin assignments: DTE to DCE" (page 133) describes the required cable pin assignments.
