magic number is really good concept. Using this concept we don't have to detach CRC(4 byte) data from the frame. This makes CRC check of the frame simple. 
        I don't remember the no. exactly. The value in CRC (4 byte wide ) appended at the tramnsmitter side such that if we caluculate CRC  for the entire frame we   get the magic no.

  as far as i know we don't face any compatibilty problem, b'cos all (?) use same cocnceppt.
