          Parameters
          ----------
          device : serial.Serial
              Serial instance.
          response_queue : Queue.Queue
              Queue to wait for response on.
          payload : str or bytes
              Payload to send.
          timeout_s : float, optional
              Maximum time to wait (in seconds) for response.
  
              By default, block until response is ready.
          poll : bool, optional
              If ``True``, poll response queue in a busy loop until response is
              ready (or timeout occurs).
  
              Polling is much more processor intensive, but (at least on Windows)
              results in faster response processing.  On Windows, polling is
              enabled by default.
