Sending SMS from mobile to gsm module through lpc2148

Question

I am trying to do an electronic notice board i.e E-NOTICE BOARD using lpc2148 and gsm module. Here basically, I'm trying to send an sms from a mobile phone through GSM and I want it to be displayed on the LCD screen.

I'm using SIM900A GSM module. I'm able to get the code everywhere for sending a message to the phone from GSM, but receiving code is hardly available anywhere.

It's really important and it would be helpful if anyone can provide the answer.

http://www.smssolutions.net/tutorials/gsm/receivesmsat/ tells you how to use AT commands to receive sms. The ring indicator will probably be set low when an sms is received.
