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.
