Where: xxx = On or Off.
This command configures the modem for the RTS
TX-IF control mode. If ‘ON’ is selected, the TX-IF
output will only be tuned on if the incoming RTS
signal is asserted (also the TX-IF output has to be
programmed On and No Major modulator faults
are presented. If ‘Off” is s elected, the TX-IF output
will operate normal ignoring the RTS signal.
