Thankyou Ioannis, Now the only choice is to change pic but i will have to just to simulate it bse i had only pic16f84, but wen i changed to pic16f877 and tried to simulate, nothing appeared on virtual terminal and proteus gave me this message ''can't perform real time simulation due CPU overlaod, what should i do?
regards

I never use simulators of any kind. And Never ever write the whole program at once. I am not Darrel or Melanie...

What I do is:

1. Whenever I change PIC, I start by a led and a button. Just 3 lines of code to read the button and light the LED.

2. Then I add a serial port to see on a terminal what is happening to the PIC.

3. Then an LCD and see if it works.

4. Then...

I have practiced simulation, now i was trying to simulate my project above but Virtual terminal is showing AT,AT, AT contineously after pressing ON the push button. What could be the problem?

Main:

IF PushButton = 0 THEN SMS

goto main

SMS:

HSEROUT ["AT" ,13,10]

HSERIN 5000, SMS, [WAIT("OK")]

HSEROUT ["AT+CMGF=1" ,13,10]

HSERIN 5000, SMS, [WAIT("OK")]

HSEROUT ["AT+CMGS=+256782277658"]

HSEROUT [13,10]

HSERIN 5000, SMS, [WAIT(">")]

HSEROUT ["BUTTON HAS BEEN PRESSED!"]

HSEROUT [26]

HSERIN 15000, SMS, [WAIT("+CMG")]

HSEROUT [10]

end
