Here is my PPP config.

Make /etc/ppp directory, then populate as follows:

options:

crtscts
19200
defaultroute
netmask 255.255.255.0
ipcp-accept-local
ipcp-accept-remote
noipdefault
connect "/usr/sbin/chat -v -f /etc/ppp/achilles.chat"

achilles.chat:

ABORT BUSY ABORT 'NO CARRIER'
'' atdt7235519

rname: dej
sword: crackme
annex: ppp
PPP.


This setup uses LCP and IPCP (parts of PPP) to negotiate the dynamic IP
addresses.  My ISP uses an annex terminal server.  It prompts for
"Annex username:" and "Annex password:".  You then get to the command
line prompt: "annex:", at which point "PPP" starts the PPP session.
You will have  to edit this to suit.

Note to crackers: "crackme" is not really my password. :-)
