Re: [Boost-users] [asio::serial_port] I can read and write synchronously, but how do I unblock when I want to end?

Hi,

- Calling close on the port: This generates an exception, which I can catch, but I was told I can't distinguish shutdown from error if I do this.

that's not true. asio will throw an "boost::asio::error::operation_aborted" error-code. HTH michi7x7
