* Step 3: Change the state of the RTS interface signal to cause the

* frequency and mode, send the next frequency and mode to the
* receiver using the TRANSFER NEXT FREQUENCY/MODE command.

* Step 5: Wait for the receiver to finish settling. The total
* settling time, including sending the next frequency and

* Step 6: Check the squelch status by reading the DCD interface
* signal. If the squelch is open, scanning is stopped.
