Dear Waqar,

first, I do not want to have you as my 'student'. I'm not your 'professor'. I just want to give help.

Are you familiar with an oscilloscope? Then you should have a look at port 2.0 pin. Are pulses fullfilling your specifications (40msec, 60msec and 800msec)?

To have a look with oscilloscope is extremely important. Without this you will be totally blind. For your purpose you need not to have a wide bandwidth type. Just 5MHz is enough. But it should be a digital storage oscilloscope, because dialing pulses are not periodic.
If you decide to proceed with electronics you should buy a good oscilloscope. For me it's similar important like solder machine and PCB router program.

I have not had the time yet to analyze your program. But perhaps some other guy will do it?

Finally, did you realize with your experiment how difficult it can be, even to solve the simplest problem? Did you realize what problems you would have had with an 8 line application? That's why so many peole told you to go step by step... They had fallen in the same traps, at the beginning of their career.

Bye,
Kai
