Can anyone help.
I am currently trying to connect 2 gprs modems over the air. My test set up is as follows.
2 pc's using hyperterminal  with 2 gprs modems connected.
My problems start when I enter the command ATD<number> the other modem rings but never answers even after I have entered ATA to answer it.

What should happen is that the modem anwers connect and I am then able to send commands over the air for it using hyper terminal. I have done the same in gsm but am unable to get to work gor gprs.

Do I need any commands other than ATD,ATA ATE?

Many Thanks for your reply

You can´t do it with hiperterminal and you can´t do it even if you create the dial-up setup on both PC's. It just doesn't work that way... With GPRS you can access the internet and even a private LAN (if there's the infra-structure needed)... But if you attach both PC's to the internet trough GPRS there's still the firewall issue on both (or if it's the same) PC's networks. I'd suggest that you use CSD and to do that...
