WvDial

WvDial (pronounced 'weave-dial' ) is a utility that helps in making modem-based connections to the Internet that is included in some Linux distributions. WvDial is a Point-to-Point Protocol dialer: it dials a modem and starts pppd in order to connect to the Internet. It uses the wvstreams library.

WvDial uses heuristics to guess how to dial and log into a server, alleviating the need to write a login script.
