    Default Opening Serial Port in ui

    Hi,
    I am so new in qt,
    I am designing a ui which controls hardware,
    So I need to reach serial port,
    I use the example code exactly, but when I compile it, there is an error :
    QIODevice::write (QSerialPort) : device not open

    I already check the hardware with Control Panel and it seems everything is ok.
    Thanks for help.

    Please use CODE tags when posting source code so it is more readable. Click "Go Advanced" and then the "#" icon to insert the tags. Paste your code between them.
