Re: [Boost-users] [asio] reopening of serial port fails - why?

Rules are:

- first start do_read(), - then start the thread - after termination of the thread an io_service_.reset()  is mandatory. Otherwise subsequent thread starts lead to  spurious behaviour. This was not clear to me and I dislike  this behaviour ...

ASIO reference explicitly states that you must call io_service::reset() before subsequent call to io_service::run(). However, you didn't have to exit the thread that runs io_service::run() - this's just matter of design. In the asio examples you can find other design choices.
