[App_rpt-users] Using CTCSS to send commands to app_rpt

Since we are discussing non DTMF methods of sending commands, I'd like to mention that the ability to send a command by changing CTCSS tone would be useful for me as I do not have a DTMF microphone but I can program a different CTCSS into the radio to send a command. While you are looking at the code please keep my request in mind. Thanks in advance, Jim WA1SOT
