Dear Michael and Jez,

Thanks for the compliments !! Sorry to have posted it.

Yes I do agree that there was not much in that write up except for the fact there is a thing called Hamming code that can be used for error correction.

I thought I will bring up this name, so that somebody who has used it will further add to it. Now I know my smart idea has not worked out :-(

Cheers

Raghu.
