According to the source code, once you set an output high or low, it stays that way until you change it, or the power fails. It's really rather simple, just decoding the appropriate DTMF digits, setting an internal variable according to the code entered, and sending that to the output port to activate relays when the last character in the sequence is received. It helps to know how to read PIC source code !
If you already have a commercial station such as an MSF5000 that has timeouts and a CW ID, and you just need some DTMF control functions, then this seems like a very reasonable way to do it.
