The PPP package contains the chat, pppd, pppdump and pppstats programs. The chat program defines a conversational exchange between the computer and the modem. Its primary purpose is to establish the connection between the Point-to-Point Protocol Daemon (PPPD) and the remote's pppd process. pppd is the Point to Point Protocol daemon. pppdump is used to convert PPP record files to a readable format. pppstats is used to print PPP statistics.
