In other words, a call to join() on that thread hangs indefinitely until data is received. My completion callback is not executed at all until data arrives for reading.

How can I force run() to return when I interrupt my thread?

Have you tried to close or cancel the serial port object? It should return your waiting handlers with an "operation interrupted" error code.

Good idea, this would have worked. However, I chose to call io_service::poll() instead to keep my thread from being blocked in the first place.

I see. I was waiting for the thread to end before I closed the serial port, I just assumed it would be unsafe to do otherwise. Thanks for the info! On Thursday, August 27, 2009, Scott Gifford wrote:

I'm currently using a serial_port object to call async_read_some(). This results in io_service::run() blocking until at least 1 byte or more can be read from the serial port. If nothing is ever sent, then I can not safely exit the thread in which io_service::run() is executing in.

I haven't used the serial_port object, but for a network socket, you can just close the network socket from another thread, and your completion handler will run with an appropriate error.

Hope this helps,
