title: Integrate microcontroller with 3G dongle
body: <p>I want to <strong><code>integrate</code></strong> a Luminary microcontroller with a <strong><code>3G USB</code></strong> dongle.</p>
  
  <p>Do all USB dongles support <strong><code>AT commands</code></strong>?</p>
  
  <p>If not then what is the <strong><code>best</code></strong> way to do it?</p>
  
  <p>Thanks..</p>
