QSerialPort flush



  • Hello, I see the flush method of QSerialPort takes a long time (about 1 ms) before executing the next instruction. Perhaps it pools the event loop. Is there a way to avoid this? I mean to execute the following instructions atomically:

    @
    port->putChar(ch1);
    port->flush();
    port->setBaudRate(newbaud);
    port->putChar(ch2);
    @

    This is because I need to change the baudrate on-the-fly. Without the flush() instruction both char are written with the same baudrate (i.e. newbaud is ignored).
    Adding the flush() function leads to the correct baudrate of the second chat, but it's delayed of 1 ms.

    Thanks
    Mark
