automatic toll collection project using RFID

[r.kuralamudhan]

i am doing automation of toll collection project using RFIDfor which i need to send the sms to user who across away the toll plaza. The sms should contain the matters such as like this "Dear customer your account balance is 100 Rs.". i need to generate this msg to each user who cross the toll booth. i am maintaining the database in MS access. i am using VB to get the data from the MS access and sending it to pic 16f877. From where i want to send the sms. my main problem is how can i send the sms whether through gsm module r through the cell phone. i search all the website abt it i get the idea that through AT commands i can send the sms. How can i write the program for the AT commands in c so that i can send the SMS through the pic16f877 to either gsm module r cell phone.

pls help me how can i do these things. My whole project is struck out by this thing[)] [)]

Connect the GSM modem to the serial port and send the AT commands through the serial port. please search the forum and site for sending SMS through a microcontroller.
