I am currently writing a program in C that will allow me to use my PDA to act as a modem for my laptop to connect to the Internet. I have managed to connect my laptop to the PDA DUN service using Bluetooth. I am also able to dial by sending ATcommands to the PDA.
But how can I communicate with the ISP that I will be connecting to? Do I have to use PPP? Or would PPP be automatically set up and configured by Windows on my laptop and my PDA to communicate with each other.
Looking forward to your advice.
Thanks and regards,
