    Default qtSerialPort maximum baud rate


    I have QT5.3 on OSX Mavericks and I am experimenting with qtSerialPort.

    Nothing fancy, I just tried the terminal example connected to a USB-Serial bridge.. To test, I have another terminal program connected to a separate USB-serial bridge and a simple null modem connection using only GND, TX and RX - no flow control.

    I can have the two programs merrily exchange data until I get to speeds beyond 230400. Beyond that, I get no communication at all.

    The bridges and the other terminal program are all proven at speeds up to 921600.

    Is there some sort of speed limit for qtSerialPort that I can find no reference to?

    Default Re: qtSerialPort maximum baud rate

    The class is merely an adapter for the platform API so it shouldn't influence the actual communication.
    Your biological and technological distinctiveness will be added to our own. Resistance is futile.

    Please ask Qt related questions on the forum and not using private messages or visitor messages.
