It's a very crude script that allows two machines that share a possibly untrusted network (e.g. WiFi) to connect to each-other and establish a secure tunnel.
The assumption is both machines can see each-other via multicast DNS, and can send UDP traffic between each-other. If you're using a WiFi network that isolates its clients, you're out of luck.
This is the raw hexdump obtained from socat from two station running LinBPQ32 (i386 and armv5)
communicating via a virtual tunnelled serial link.

| 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. |
