PS: I think you might need to mark the beginning of "packet" in some way; otherways after (unintentional) entering the wrong password (e.g. noise on the phone line - I suppose DTMF is going to be transferred via phone) you might lose trace where your program is... Some sort of synchronisation, and perhaps some checksum, too.
