What program is needed to establish a PPP link to another computer?
wvdial – PPP dialer with built-in intelligence. wvdial is an intelligent PPP dialer, which means that it
dials a modem and starts PPP in order to connect to the Internet. It is something like the chat(8)
program, except that it uses heuristics to guess how to dial and log into your server rather than
forcing you to write a login script.
