 help me..where to edit code…

 

this code is transmitting commands to hyperterminal but not working with mcu

 

#include<avr/io.h> //This is the header for AVR Microcontroller
#define F_CPU 12000000
#include<util/delay.h>
#include”uart.h”  //header file to program uart

int main(void)
 {DDRC=0x00;PORTC=0x0f;DDRB=0x0f;
  uart_init();  //initialisation of uart
  while(1)
  {if((PINC&0x0f)==0x0f)
   {PORTB=0x0f;}
   else{
   PORTB=0x03;
   _delay_ms(6000);
   uart_string(“ATr”); //function to pass a string
   _delay_ms(2000);
   uart_string(“ATE0r”); //function to pass a string
   _delay_ms(2000);
   uart_string(“AT+CMGF=1r”); //function to pass a string
   _delay_ms(2000);
   uart_string(“AT+CMGS=”+91**********”r”); //function to pass a string
   _delay_ms(2000);
     uart_string(“op is ok”);
 _delay_ms(5000);
  uart_char(0x1a);
  _delay_ms(6000);
  }
 }}
