I think, all of us are wasting our precious time. The method you just explained is a nice and viable solution which I already stated here and explained him on email as well.

All he wants from us is to write code for him. So if we have to attend his posts, let's quote our rates and thats all (sorry Craig we really don't want the forum to be an advertisement palce.)

Waqar, you are closing doors yourslef, one by one. Shouting, yelling, complaining, giving temptations wouldn't yield any results.

As far as commands to use for pulse dialing detection are concerned, I can do this task using the combination of just about 92 instructions of 8051. You can also do it. Just try !!

Good Luck
