The Parrot can be used as a functional replacement for the built-in parrot that was removed from the MMDVM Host when the networking was added. The Parrot is very simple minded and can only handle one client at a time and is therefore not suitable for use as a shared resource via the Internet.
The YSF Gateway allows for use of Yaesu Wires-X commands from the radio to control the listing and access to the various reflectors (rooms in Wires-X parlance). It optionally sends System Fusion GPS information to aprs.fi.
The DG-ID Gateway allows the use of the DG-ID setting on the radio to control access to the different System Fusion network systems. It optionally sends System Fusion GPS information to aprs.fi.
The Gateways have ini files that contain the parameters for running the software. The filename of the ini file is passed as a parameter on the command line. The Parrot takes the UDP port number to listen on as an argument.
