QSerial port Issue

  • i am coding an application that communicates with a device over LIN Protocol using the uart.
    The device sends data and is waiting for a reply in a specific time, it seems that i am not replying.
    I set the buffer size to 1 Byte so that each command i can reply promptly.
    I connected another application to another usb/serial port to listen to my replys from the 1st usb/serial port. I see there are replys. But when i set the buffersize to 1 Byte i don't see any reply back.
