2.4.2 | PPP |
PPP is a standard serial-line
encapsulation method (described in RFC 1332 and RFC 1661). This
protocol can, among other things, check for link quality during
connection establishment. In addition, there is support for
authentication through Password Authentication Protocol (PAP) and
Challenge Handshake Authentication Protocol (CHAP).
