    Default qextserialport cant open ports in windows 7

    Hi,
    I was trying to open the COM ports using the qextserialport example that came with it. It worked fine on Wondows XP. But in Windows 7, it did not; that is port opening was unsuccessful. I even tried to prepend the "\\\\.\\" to the com port name to have something like: "\\\\.\\COM6", but it still failed.
    Does anyone know what might be the problem, or the workaround for this?

    Now that you have mentioned that I also suspect that. But, I was using it as the user with administrative privileges, unless something additional has to be done.
