title: The third byte postion determines the length of that string. I want to then add a ":" at the end of each byte position

  <p>the third byte tells me how long the string will be
  so i want a ":" added at position 6
  like below</p>
  
  <pre><code>41 2B 06 01 73 00: 41 AB 0D 48 01 CF FC 80 CF FC 80 D8 05;
  </code></pre>
