      <div>On the raspberry pi, it is easy to use the wiring pi
        program and a modification of K0KN's astled script for PTT.
        However, I have no idea how I would wright a script to tell
        Allstar that there is a COR detection when the GPIO input on the
        pi has gone high. </div>

      <div>If anybody knows more about it, could they help with a

        return a value 1 or 0. How do I pipe this to Allstar COR? </div>
