Extensible software to control amateur radio transceivers and related hardware like GPIO-pins etc. and to integrate clients with third-party software using application specific extensions.
trx-control consists of trxd(8), a daemon to control the transceivers and other hardware, and, trxctl(1), a command line utility to access trxd(8).
Software that wants to make use of trxd(8) should implement the protocol and talk to trxd(8) directly over the network.
trxd(8) listens on port 14285 by default for incoming connections over plain sockets and can optionally listen for WebSocket connections. It supports both IPv4 and IPv6.
The actual transceiver control is done using protocol drivers written in the Lua programming language. Definitions for specific transceivers are written in the YAML text format.
This way new transceivers can easily be supported by supplying a corresponding protocol driver and transceiver defintion.
See https://lua.org and https://lua.msys.ch for more information on Lua.
There is a Matrix room #trx-control:matrix.org to discuss trx-control:
