Re: malformed packet

I think I may have narrowed down my malformed packet problem....but I am 
not sure how to fix it.

It appears that my offset is just not correct. I have manually counted 
the bytes as I went...but I still come up with a different
value than I expected.

If I get a "unknown code"... then the packet becomes malformed. But if 
the code exists, it dissects the bytes properly and works fine.

Attached is the code.

Any help is greatly appreciated.

Thanks,
Brian
