title: Carriage return (0X0D) between data sent over Xbee S1 modules
body: <p>I'm trying to send the following hexadecimal block of data:</p>
  
  <pre><code>45,  0,  0, 63,  0,  0, 40,  0, 40, 11, 6E, DC,  A,  0,  0,  1, C0, A8,  1,  5, 9D, B3, 22, B8,  0, 4F, 2E, 47, 61, 62, 63, 64, 65, 66, 67, 68, 69, 6A, 6B, 6C, 6D, 6E, 6F, 70, 71, 72, 73, 74, 75, 76, 77, 78, 79, 7A, 61, 62, 63, 64, 65, 66, 67, 68, 69, 6A, 6B, 6C, 6D, 6E, 6F, 70, 71, 72, 73, 74, 61, 62, 63, 64, 65, 66, 67, 68, 69, 6A, 6B, 6C, 6D, 6E, 6F, 70, 71, 72, 73, 74, 75, 76, 77, 78, 79
  </code></pre>
  
  <p>Which is originally a UDP packet over <code>Xbee S1</code> module to another <code>Xbee S1</code> module</p>
  
  <p>When I read the received block of data using <code>X-CTU</code> the received data is:</p>
  
  <p><code>45 00 00 63 00 00 40 00 40 11 6E DC</code> <strong>0D</strong></p>
  
  <pre><code>0A 00 00 01 C0 A8 01 05 9D B3 22 B8 00 4F 2E 47 61 62 63 64 65 66 67 68 6A 69 6A 6B 6C 6D 6E 6F 70 71 72 73 74 75 76 77 78 79 7A 61 62 63 64 65 66 67 68 69 6A 6B 6C 6D 6E 6F 70 71 72 73 74 61 62 63 64 65 66 67 68 69 6B 6C 6D 6E 6F 70 71 72 73 74 75 76 77 78 79  
  </code></pre>
  
  <p>Note the Bold byte (<code>0D</code>) which is not related to the sent data?</p>
  
  <p>Any one can guess the reason? is it the configurations?</p>
