Protocol Specific Configuration
Non-E1/T1 HDLC.FRAME Configuration Values
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 signalis 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.

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