Behavior is apparently no different than handshake none. Works fine with windows-specific code which sets the DCB as follows: {{{ dcb.fOutxCtsFlow = true; // Enable CTS monitoring dcb.fOutxDsrFlow = true; // Enable DSR monitoring dcb.fDtrControl = DTR_CONTROL_HANDSHAKE; // Enable DTR handshaking dcb.fOutX = false; // Disable XON/XOFF for transmission dcb.fInX = false; // Disable XON/XOFF for receiving dcb.fRtsControl = RTS_CONTROL_HANDSHAKE; // Enable RTS handshaking }}} Couldn't find where the DCB is set in asio...",Bugs,new,To Be Determined,asio,Boost 1.54.0,Showstopper,,,
