Configuring Cwdaemon With Trusdx

The ham radio logger program xlog supports CW keying, but I needed to figure out how to enable it. I was using Debian stable, which shipped with cwdaemon 0.10.2 — a version that doesn’t support configuring serial port control lines, and trusdx doesn’t use the default setup. I needed to manually build the latest cwdaemon (0.13.0) to have the -o flag.

Here’s the command line I needed to start cwdaemon with:

./cwdaemon -d ttyUSB0 -x n -o ptt=none -o key=RTS

It is super useful to know that both cwdaemon and rigctl (hamlib) can use the same device file at the same time (one is only pulling the control lines, the other one issues CAT commands).

Currently, xlog spins up rigctl, but I want to figure out if it recognizes an already running daemon because I don’t want the radio to reset every time I restart xlog, and I may also have multiple programs that want to access the radio.

hamlib serial config params for Trusdx:

serial_speed=115200,rts_state=OFF,dtr_state=ON
