The order of operations is: create serial_port, call async_write to send some data over the port, call cancel to cancel the write operation, enter io_service. I would expect the write completion handler to be called with the error_code argument set. Instead, no error_code is set and some bytes are transferred.",Bugs,closed,Boost 1.40.0,asio,Boost 1.39.0,Problem,invalid,,
