WOW. memories. ...
If your distribution uses KDE, then yes, KPPP is very easy to configure and workd like a champ.
Similarly, gnome has gnomeppp which makes the whole process handy, too.
If you are feeling brave / robust, you can play around with tin and pppd like we had to in the old days.
My point is that there are many mnay ways to make it work, and some are more user-friendly than others, but as long as the ISP supports PPP you should be fine (I can't think of any dial-up ISPs that don't use ppp).
