Protocol Specific Configuration

HDLC.FRAME Configuration Values

Chapter 4 33

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.

Select Word

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.
