I hope you are well aware of the fact that N72 creates virtual serial port on you PC. you feel that you are working on a serial port whereas in actual you are emulating serial port on USB. So keep this in mind

hi,
i m also working on the similar project. i m trying to sens sms by interfacing microcontoller (8051) with NOKIA 6080 .. i m using AT COMMANDS.
i m able to send sms when i connect nokia 6080 with pc serial port and then send AT commands through hyperterminal.... i just send ... AT+CMGS="9865682569"message....with this i was successfully able to send sms.....
i have written program for the same in 8051....but when i connect my 8051 with 6080 ... i do not get any response.....
when i connect 8051 circuit (serial port o/p) with pc then i m able to see the AT commands that r send by 8051 on hyperterminal.... the commands appear without any error.....

i m using DKU-5 cable which has RS-232 o/p on one side......

plz... tell me where is the mistake....

also regarding post send by ABBAS1707...... i want to how much delay is there in the delay() function for the code below posted by ABBAS1707....
is it 1ms....

CODE:

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);          

}
