I don't imagine the *chip* could be hacked. It's a special which sends
packets down a serial line. But the *wheels* could be hacked ok.

If you want to communicate with the chip itself, then the protocol is
documented in several places. It is one-way, and sends either two or
three bytes of information.

char *p="char *p=%c%s%c;main(){printf(p,34,p,34);}";main(){printf(p,34,p,34);}
This message made from 100% recycled bits.
I don't speak for Alcatel      <- They make me say that.
