++ - The creadersync example should not return true when an empty buffer was read.
++ - Improved data receiving in creaderasync example. Received data should be
++ accumulated at each triggering of readyRead() during wait timeout.
++
++ - QSerialPort:
++ * [QTBUG-33938] Fixed crash when closing serial port on Windows. Now the
++ signals/slots are used instead of overriding the QWinEventNotifier::event().
++ * Improved the low-level data writing on Windows. Now a whole writeBuffer
++ is written instead of chunks.
