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

Hello,
hope to have found a solution.

The problem seems to be caused to a "random" readCompleted() callback function recalled with error=0 and byteTransferred=0 - while Wireshark shows me that the packet was received!
At the beginning I only exit from the function but the TimeoutExpired arrived.
I corrected the procedure adding the rearm of the async read in case of error==0 and bytes==0. Now I'm able to recover the packet and go on!

I don't know why the callback function is called with bytes=0, but that's the way .. 

Thanks!
