Robert -
Just use the serial_port like you would a TCP/IP socket. For example,
I do this in one of my classes reading streams from hardware:
serial_port.async_read_some( boost::asio::buffer( in_message, MAX_MESSAGE_SIZE ),
boost::bind( &SerialClient::read_done,
shared_from_this(),
boost::asio::placeholders::error,
boost::asio::placeholders::bytes_transferred ) );
Why are you having to poll?
