Description

I am using pymodbus REPL server and client for modbus rtu communication with two usb adapters. Unfortunately I wasn't able to configure another baudrate, parity, stop bits and other serial settings for the server. I checked the config of the serial port with the command stty. In my example the server wasn't set to 38400 baud. I was able to set it manually while running the server. The client settings are fine.

Are there command line parameters to set those properties? I haven't found them in the example videos, docs or code.

Code and Logs

pymodbus.server --verbose run -s serial -f rtu -p /dev/ttyUSB1 --baudrate 38400 -u 1 -r 2

pymodbus.console serial --method rtu --port /dev/ttyUSB0 --baudrate 38400

Will take a look and revert.

Thanks for the bug, the serial args are being dropped silently. I will have a fix in a day or two.
