Re: [boost] [Newbie] Problem receiving data with asio::serial_port

In Asio, every time you call an async function, you will eventually get a completion callback. So every time you attempt a read, two callbacks will always get generated, one for the timer, one for the read operation. This is true even if one of the operations gets cancelled - the callback will happen to contain an "asio::error::operation_aborted" error, but will get called.

thanks a lot, Ruben. I think I changed the code to wait/align all the notifications. My last doubt is the 'error=0 and bytes=0' notification: as I said I handled it with a re-launch of a new async_read. Thanks again, Stefano
