First time every thing is ok but second time mobile's reply is "OK" but debugging in proteus this string shows "O" one the second location and "k" is in third location of the string while first location of the string shows "0X0A".

For more reactions you might want to explain your problem a bit further. I can understand what is going on, but I do not entirely know what you want to happen.
I suspect you want to get rid of the 0x0D character (Newline I believe). You can accomplish this by flushing your serial port after your loop. Something like this might do the trick:
| Code: | while(1)
{
if(input(pin_a0))
{
delay_ms(500);
puts("AT");
gets(mobile);
if(stricmp(mobile,refr))
{
puts("ATD 00923215702782");
gets(mobile);
}
}
while (getc()); //Flush any remaining characters
} |
Hope this helps,
Jos |

setup_vref(FALSE);
while(1)

Your 'refr' string is in lower case. The modem sends an "OK" response in
upper case. |

Again no success. In proteus debugging at first time when I press the button both string have "O" and "K" in their first and second location or byte.
But at the second press of switch the string from mobile shows "0x0A" at the first location "O" at the second location and "K" at the third location. So the strcmp fails.
How can I solve it ?
Thanx |
