I&#39;m using boost::asio::serial_port to read and write to a serial port device. I do the reading inside a boost::thread to take advantage of RS-232 being full-duplex. My read calls are like this one:<br><br>BYTE b;<br>read( m_SerialPort, boost::asio::buffer(&amp;b,1) );<br>
<br>Everything works OK except for shutdown. When I want to end the thread, it&#39;s almost always blocked in a read call. How do I unblock it? I tried:<br><br><ul><li>Calling close on the port: This generates an exception, which I can catch, but I was told I can&#39;t distinguish shutdown from error if I do this.</li>
<li>Stopping the io_service I passed to the serial_port&#39;s constructor. This had no effect, the thread remained blocked on the read call.<br></li></ul><br>-- <br><div>
