    Default Serial Port communication

    Hi!
    I am trying to communicate to a serial port device. I would like to use "QExtSerial". I downloaded and build the QextSerial but I need some help to use it correctly. Could anybody share an example with me?


    Thank you

    I was successful using "QExtSerial" code. Actually I changed and shortened the code to be able to embed it to my original code. If anybody needs an easy serial comm. code just send me a message....

    So you didn't compile it. The build failed. It seems that you forgot to run qmake or something. Looks like the compiler tries to compile the unix version.

    You shouldn't have issued "qmake -project". Go ahead and read the docs about what it does.
