FreePPP

FreePPP is so far the best free PPP dial-up software there is out there, i even use it myself. FreePPP 2.5 brings a new level of power and ease of use for accessing the Internet via a modem. Version 2.5v3 corrects a potentially nasty bug that could cause FreePPP to crash when getting a busy signal. In addition, a new modem database is included and an updated version of the FreePPP Menu is included.

The Beta version is the most current one, however it should not be used for your primary use, as it is not a full release. Check back later, It'll be here once its out.
