I am doing a little science fair project and I need to connect two computers together using two dial-up modems, two phones (mic. to spkr. and spkr. to mic.), using no phone line, just plain old phone cable. I have powered the cables with 9V batteries and can use the phones as intercoms, but can I use them to establish a dial-up connection between two PCs? The reason I am doing this crazy set up is because I plan to hook the mic's and spkr's up to ultrasonic sound converting circuits and have the communication be done over air via ultrasonic sound.
Thnx for the help!
