code: def _sendBinaryData(port, data):
      
      _reset(port)
      time.sleep(leadInOutDelay)
      for digit in data:
          _sendBit(port, digit)
      time.sleep(leadInOutDelay)
docs: Send a string of binary data to the FireCracker with proper timing.
  
      See the diagram in the spec referenced above for timing information.
      The module level variables leadInOutDelay and bitDelay represent how
      long each type of delay should be in seconds. They may require tweaking
      on some setups.
