I think you must go through these files carefully..
Nokia 3310 FBUS Protocol information
Nokia FBUS 2.0 information

Reference links:
http://www.embedtronics.com/nokia/fbus.html

Additionally look in the forum carefully you will find discussion regarding nokia 3310 FBUS implementation.

still if u want to go by the present system.....
the above links would do you loads of good..

but take care nokia 3310 does not allow sms in text mode..........
moreover The FBUS baudrate is 115200bps,does not respond at lower baudrate like 9600bps....
so how are u going to generate 115200 using 51..
?? little tricky there

@ajay i dont see the future of fbus if u think there is some ...then i can have a library written for it for 8051
watsay??

well there is future of FBUS.. because its becoming the basic protocol which is used to reprogram the mobiles phones which is called flashing. on old phones still MBUS is used for flashing.. but new phones are using FBUS..

i hope you have gone through the websites i posted. They include complete information of what you have to do in your code.

Regarding generation of 115.2K baudrate.. use AT89C52 and make use of timer 2 to generate this baudrate. Its very easy to do that not much tricky.

You can make use of datacable of Nokia 3310. You need to make sure that the DTR signal has to be High and RTS has to be low. If you want to enable FBUS. This is only if you are using a datacable.
