I'm having trouble with my serial communication across the serial port, and want to get more diagnostic information by going to the native level. The serial port hangs occasionally on a synchronous read_some call, and I haven't been able to figure out why. Ideally, I'd like to build a timeout into the synchronous call.
AFAIK read_some() should only block if there is no data to read at all. You could check for that with: boost::asio::socket_base::bytes_readable command(true); socket.io_control(command); std::size_t bytes_readable = command.get(); Or you implement your own read() function with async_read() and deadline_timer, like here: http://lists.boost.org/Archives/boost/2007/04/120339.php Chris -- echo mailto: NOSPAM !#$.'<*>'|sed 's. ..'|tr "<*> !#:2" org@fr33z3
