first of all thanx for reply,
Before post here , I've communicate two GSM modem in client and server mode and they are working as per my expectation and i got Bi-directional communication!
but I'm not getting connection from GPRS modem( in server mode) to web application(client mode) as I'm getting time out at client,
But as i told earlier, I've successfully established connection from client (GPRS MODEM) to server(web application) so what about that?
More-ever I've seen few product on internet having same application as i need here, so what about that?
