            Move-construct a basic_serial_port from another.
          
basic_serial_port( basic_serial_port && other);
This constructor moves a serial port from one object to another.
                  The other basic_serial_port object
                  from which the move will occur.
                
            Following the move, the moved-from object is in the same state as if
            constructed using the basic_serial_port(io_service&) constructor.
