How to use QSerialPort for double thread

[nistar]

The Qt documentation says:


The serial port read in your case probably happens in a separate thread.. You need to make sure read and write happens in the same thread in which you open the port. Hope that helps..

But how to do it?
I think that my program use only one thread.

Added after 15 minutes:

My guess is that the problem is your missing Q(Core/Ui)Application instance.
So the main thread is not "adopted" as a QThread and thus lacks the necessary event dispatcher for socketnotifier's event handling.
