This function will return the number of bytes waiting in the receive queue of the serial port. It is included primarily to provide a complete QIODevice interface, and will not record errors in the lastErr member (because it is const). This function is also not thread-safe - in  multithreading situations, use <a class="el" href="classWin__QextSerialPort.html#a22">Win_QextSerialPort::bytesWaiting</a>() instead.
