Reserved (0)		AZR	AZT	0	CWEN	RSIG	DSIG	RTS	Reserved (0)
All reserved bit positions must be filled with zeros (0).

AZR - (Z7340A only) Analyzer terminal for received data

Enables this terminal for monitoring frames received on the port. All received frames are copied, and the copy delivered to the receiving application for this terminal. This terminal cannot be used to transmit frames.

AZT - (Z7340A only) Analyzer terminal for transmitted data

Enables this terminal for monitoring frames transmitted on the port. All transmitted frames are copied, and the copy delivered to the receiving application for this terminal. This terminal cannot be used to transmit frames.

CWEN - Enable the use of formatted Control Write requests

If set to one (1), this bit enables the use of formatted control write requests. See the “Request Specific Processing” section of Chapter 3 “Using HDLC.FRAME Protocol” for the format to be used.

RSIG - Report status on CTS or DCD signal state change

If set to one (1), this bit enables an unsolicited status message to be delivered to the receiving application when either of the CTS or DCD signals is dropped, and when both CTS and DCD are raised.

If this bit is set to zero (0), the HDLC.FRAME terminal does not report the state of the CTS and DCD signals.

DSIG - Go down on loss of signal

If set to one (1), this bit will cause the HDLC.FRAME terminal's status to be changed to DOWN when the CTS or DCD signal is lost. At the same time, an unsolicited status message is delivered to the receiving application. The RSIG option has no effect in this case.

If this bit is set to zero (0), then the HDLC.FRAME terminal continues to operate whatever the state of the CTS and DCD signals.

RTS - Control the RTS signal on transmitted frames

If set to one (1), this bit will cause the RTS signal to be raised when the HDLC.FRAME terminal has a frame to transmit. When CTS is raised by the remote device, the frame is transmitted after frame transmission RTS is dropped, unless there is another frame to transmit.

If this bit is set to zero (0), then RTS is kept raised as long as the HDLC.FRAME terminal is enabled.

Reserved (0)								BADFR	Reserved (0)
All reserved bit positions must be filled with zeros (0).

BADFR - Bad frame completion

If set to one (1), this bit causes received frames with bad CRC or received aborted frames to be passed up to the receiving application with a status code indicating the error condition.

If this bit is set to zero (0), then all received frames with bad CRC or received aborted frames are discarded.

Protocol Option Word

The option word is not used with the HDLC.FRAME protocol.
