    Hello!

    It is possible to change serial port baudrate to value that is not in list? I want use 250k but it is not on selectable list.

    Second question is, when we create new ModbusChannel there is option to set trigger from "application" but how to use this? any example?

    Thanks for answer.

    Thank you for answer.
    Its my own DIY I/O module. I want increase baudrate to minimize delays.
    Could you also answer for my second question? Maybe simple example?

    Another question about Modbus.

    Modbus COM, 3.5.11.20 (latest). On tab SerialPort Parameteres there is no baudrate 38400.
    But you can set it with tab General, and seems like it's working.
