Dear friends
m designing a gsm modem based vehicle theft alert system.in which if the door is opened u will get the message on ur mobile abt theft.
now i want to send back message to controller to stop the engine.uptill this step i have done the coding.
now the problem arises that i want my controller to detect only one mobile number thru which stop engine command has to get activated..and not thru any other mobile number.
wht AT command to use for this?
thanks
