View source for DATV repeater DTMF commands

The ATV repeater controller includes a DTMF decoder enabling off-air control of some repeater functions.

The actual command sequence is in the format *xx# - the length of the sequence is variable so a command could be *123456# if required.

The actual command for each function is entirely flexible and is set in the config file.  

It is recommended that some command sequences such as shut down are not publicly available and have been grouped in the example config file as keeper commands - [[Repeater Controller configuration]].

The following functions can be changed using DTMF commands - 

====Suggested keeper functions====
dtmfkeepertxoff
