4.6 Dial-up Service-PPP
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. Modem / PPP access is
almost identical to connecting directly to a network through JetBox 8100's
Ethernet port. Since PPP is a peer-to-peer system.
