You guessed wrong, the Internet uses checksums instead of the more advanced 
Hamming codes.  AFAICT, you are trying to find the actual code that 
accomplishes the necessary tasks on your machine.  Good luck on that.   If 
you have Linux you could presumably find it after a persistent search.  On 
Windows the code is probably (repeated several times of course) in different 
DLLs with catchy names such as M13BFTSLK.DLL.  There are a few thousand DLLs 
scattered around your hard drive.

This article is a nice overview of the general subject.
