Dummy rigctld implementation for GPIO control of radio PTT
#!/usr/bin/env python3
"""
Dummy rigctld implementation for controlling a radio PTT signal via a GPIO
pin.
This is intended for devices like the NWDR UDRC-II and DRAWS boards, which
attach to the top of a Raspberry Pi 2/3/4/5 single-board computer and provide
control signals for PTT and COS along with an audio interface for digital mode
operation.
