8051 serial interface

I think mobile Phone cannot be interfaced to the microcontroller using RS232, you should interface it by hacking its headphone cable..

Sounds like an interestign project. I have some experience setting up the MCU port and crossbar for UART applications. Do you have the data sheet for the particular MCU you are using? Do you plan to connect your MCU to a PC a review the data in a hyperterminal session?

serial cable interface of 8051 with mobile phone

void main()
{
initUART();
delay();
sendString("AT+CMGF=1"); // command to select text mode
sendChar(13);
delay();
sendString("AT+CMGS=\"0999999999\"");// here 09999999999 is recepient's number
sendChar(13);
delay();
sendString("Hello!"); // Hello! will be sent
sendChar(26);
sendChar(13);
}
