title: Is there a simpler example available for performing serial communication using EAAccessory?
body: <p>I am writing an iPhone application that needs to send and receive data over the serial connection.  I have been studying Apple's <code>EADemo</code> found here: <a href="http://developer.apple.com/library/ios/#documentation/ExternalAccessory/Reference/EAAccessory_class/Reference/Reference.html" rel="nofollow">EAAccessory reference</a></p>
  
  <p>The problem is that I am finding this example too complex to take in. Is there a simpler example available for how to send and receive to and from a connected accessory over a serial connection? </p>
  
  <p>I'm looking for something like sending four integer values to the accessory, and then sending them back to the iPhone using a <code>const char</code> buffer.  </p>
