DTMF Command to shut down repeater

Greetings folks! Just built up a repeater and all is working as it should. Next, I have been searching how to use DTMF to shut down the repeater if necessary. As you would with typical repeater controller. As such, looking for information on how to do this.

Thanks!

COP command 3.

Thanks for responding. But I am not clear any of these commands will shut down the RF hardware due to a malfunction. Control IO for example to remove power from the transmitter. Also, I am not clear on how to use the COP commands.

So for example, using DTMF what is the sequence for the COP commands. Sorry, I am a new user.
