sending an SMS using sim900A with PIC16F877a in mikro C pro for pic

[Jeffin Jacob Philip]

is this code correct . . .

its not working

is there anyone to help me....

//crystal 20Mhz
 void main()
{
TRISD=0;
PORTD=0xff;
Delay_ms(1000);
PORTD=0;

UART1_init(9600);
Delay_ms(10);


UART1_Write_Text("AT\r\n");
Delay_ms(2000);

UART1_Write_Text("AT+CMGF=1\r\n");
 Delay_ms(2000);


UART1_Write_Text("AT+CMGS=\"+919895595189\"\r\n");

Delay_ms(1000);

UART1_Write_Text("OK...Its working");
UART1_Write(0x1A);
Delay_ms(2000);

         Delay_ms(2000);
         PORTD=0xff;
          Delay_ms(1000);
PORTD=0;
         }

Try this. If it still doesn't work then switch to PIC18F device.
