i want to connect my nokia n73 mobile with 8051. cau u help me how to design a cable for it, which can connect these two(microntroller and mobile phone).actually i am a beginner. i have a data cable with USB cable ,wiyh which i connect mobile with computers(pc suite).
at commands work properly with hyperterminals, but i want to connect it with mobile.
thanks
Buddy, I am trying to build a HACS system, in which user can control his household appliances just by using his phone and getting appliance updates from the other end by the microcontroller using an SMS through the mobile connected to microcontroller.. ..... So, in my model i have a microcontroller connected with a mobile, by which the appliances can be switched on and off. So, this describes the structure depicting my commanding section. The commanding section is done. ,.,.,.,. Now, for the updating section.. i want to connect the mobile with microcontroller so that microcontroller on getting info from the sensors connected to it, will initiate an SMS thourogh the mobile to us. Now, as u said that 8051 can't be interfaced directly with mobile modem(N73), so i included PC to Interface these two using hyperterminal. But again there lies a severe problem, that the microcontroller and mobile will be connected to two different com ports and using two different hyperterminal windows.

Send SMS via the PC and forget the phone. Google 'Send SMS from PC' for how to do it.
Mama mia! what a mess! why bother when this can be solved in so many trivial/less trivial but practical ways...!!!!
"I have this thingy and I WILL use it" (stamping little feet).
This would be so simple if s/he would use a 'regular' modem with a plain serial interface.

No, that is not (just) a "modem" - that is a Phone!
As previously mentioned, this is the root of your problem - so don't use it!
A Phone is not an appropriate device for this application.
You need a proper GSM modem (or module) that is specifically designed for embedded use,
'Cause right around now is senior design 'crunch time' (at least I HOPE thats what this is).
In fact, it is a "serious smart-phone":

ok i got ur point sir, now plz tell me from where i can get gsm module ready to use in embedded projects having serial port?i live in india. any website link.
arround how much does it cost?(any rough idea)
Several here: www.8052.com/.../174430
they should all have lists of their worldwide distributors.
RS & Farnell now sell such stuff.
And there's always ebay.
