While there are winmodems that can be made to work under linux, what I will tell you is this. You only need to try to configure en external modem one time to be sold on them for the rest of your life. Even in windows they are easier to configure as they almost never need a special driver like all winmodems do. Go get an external modem. You can pick one up for $50.00 easy and $25.00 if you catch a good deal. It is worth EVERY PENNY. Even if you primarily use windows. I find that it connects faster and stays connected longer and downloads at much closer to the max for my phonelines more of the time, unlike my ol winmodem, that would start downloading very fast and then gradualy slow down to a crawl.
