GPRS conn using sockets

Hello all again.

I have two Fastrack modems which i'd like to comunicate via GPRS. I have a listening socket in one of them. The thing is that I need something to start the connection on the other when the modem starts. I've got all the IPs and data I need, but I just don't know how to start the connection (an opening socket I think...)

Could anyone give me a hint about this? Thank you very much in advance.
