title: Interpreting Serial Port Data
body: <p>I have a speed radar system that has a com port on the back.  I've connected to it by a USB serial adapter.  The com port can be used to connect an external display, or connect to a video system.  I'm using RealTerm to connect to it.  The information being displayed doesn't appear to make any sense.  The information being displayed does change if the radar system detects changes in speed.  </p>
  
  <p>This is basically what I see on the screen:</p>
  
  <p>No speed:</p>
  
  <pre><code>À    À    À    À
  </code></pre>
  
  <p>Changes in speed:</p>
  
  <pre><code> Ä  Ä  Ä  Ä  Ä
  </code></pre>
  
  <p>My end goal is to pipe the data into our CCTV system.</p>
  
  <p>Can someone point me in the right direction to start with?</p>
