PPP (Point to Point Protocol) is used to run IP (Internet Protocol) and other network protocols
over a serial link. PPP can be used for direct serial connections (using a null-modem cable) over
a Telnet link, and links established using a modem over a telephone line. Usually pppd is called
by other daemon, like PPPoE, PPTP, and Wvdial.
