ppp | Point-to-Point Protocol (PPP) daemon | Mehr ...
The Point-to-Point Protocol (PPP) provides a standard way to transmit datagrams over a serial link, as well as a standard way for the machines at either end of the link (the "peers") to negotiate various optional characteristics of the link. Using PPP, a serial link can be used to transmit Internet Protocol (IP) datagrams, allowing TCP/IP connections between the peers.
