  <p>I trying to open MY USB dongle, so I can send SMS. Following is my code for opening</p>
  
  <pre><code>#include "MyClass.h"
  #include &lt;qstring.h&gt;
  #include &lt;qdebug.h&gt;
  
  
  int main()
  {
      QextSerialPort *port = new QextSerialPort("COM7");
      port-&gt;open(QIODevice::ReadWrite);
      cout &lt;&lt; port-&gt;isOpen();
  
      system("pause");
      return 0;
  
  }
  </code></pre>
  
  <p>When I run this code, what I get is </p>
  
  <pre><code>QWinEventNotifier: Can only be used with threads started with QThread 
  1
  </code></pre>
  
  <p>This shows the port id Open, but what about that message? Does that means I can't proceed with other code? I want to know this before I code anything else. </p>
