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?
