The warnings you mentioned above about data packing are most likely coming from using an incorrect pack format for the data passed to pack. The 'c' format expects a signed 8 bit value (-128 to 127); since you are passing pack a value between 0 and 255 (an unsigned value) you need to use the 'C' format instead. See perlfunc for more details about pack formats.

Update: Link fixed.

  • Posts are HTML formatted. Put <p> </p> tags around your paragraphs. Put <code> </code> tags around your code and data!
  • Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
  • Read Where should I post X? if you're not absolutely sure you're posting in the right place.
