Yep, figured that one out after it was too late. It has now been pushed into a separate branch. |

Closing this request so I can apply the changes to the dev branch instead |

These changes allow to user to specify a Raspberry Pi GPIO line that keeps Dire Wolf from transmitting when the line is active. I implemented this for an APRS igate/digi that will be at a site that will be sharing air time with a packet messaging system. The ham club would like the existing system to take priority and inhibit the igate from transmitting when DCD is detected on the other frequency, hopefully avoiding desensitizing that receiver. It ties into the existing DCD code so Dire Wolf will give up if it waits too long for a clear channel.
I'd imagine you'll want to change this code to suit your style, but feel free to use the idea.
