I have PC-A with xp and ubuntu with a 56k dial-up modem and LAN connected to my router and I want to share it's internet to PC-B with windows 98 and 56k modem over phone line (see primitive diagram below).
How can I accomplish this task (this is a project I know it is dumb)
Setup the first PC as a gateway and a dial-up server (not sure if you can even do that with XP), connect the modems together between the 2 computers. Dial into the server PC with the Win 98 machine. How to actually configure all this so it works will take a bit of work though.
I believe this is refereed to as a Null Modem Cable. You would use something like Hyper Terminal to set this up i'm thinking. Sort of like settin gup a Cisco Router (the industry kind not the ones in your home)
Ok Scratch that..
It can be done, but the software is the trouble. You can communicate using a dialer to dial to each other. Finding the software may be another problem.
Unlike Ethernet i dont think you have to reverse the end on a phone cord.
