SD will still key based on the RTS line, but the CTS line is used as a key-
line control for the other radio. CTS is asserted immediately following
the receipt of RF data, but data will not be sent out the
port until after the CTS programmable delay time has expired. (This
gives the other radio time to key.)

This command deactivates the transmitter after it has been keyed with
