Hi

Please let me know what is the error in the following code. I am doing a tracking project. My vehicle unit has a simcard with sms message stored on it. When the unit powers up it reads the sms and enables the GPRS module(xxxgprs. com is my APN). It establishes the GPRS TCP/IP connection to my server on port 29999.

I created a php program which listens the port 29999 to receive the data transmitted by the unit....
