You don't set up a chat script. What you do (in general terms) is:
1. Set your modem to auto-answer. Exactly how to do this varies by modem,
mainly in how you get the modem to store a revised configuration, so consult
your modem docs for this part.
2. In /etc/inittab, add a line that has whatever getty app you use (mgetty,
agetty, getty_ps, etc.) watch the modem line for a call. Then reinitialize
init so the process starts.
3. Have the incoming call run pppd . There are two basic ways to do this:
a. the getty process can run something other than login,
specifically a script that starts pppd . You'd then
have pppd authenticate using pap or chap.
b. the getty process can start a normal login. In this case,
the accounts that run ppp connections would have the
shell entry (/bin/bash, usually) replaced with an
entry that runs a script to start pppd . This method
relies on ordinary userid/password authrntication.
This is only a sketch of the process. The PPP HowTo has more sketchy
information on it, possibly enough that with this helpm you can work out the
details for yourself. If you like, I can provide a complete setup using
agetty .... but only old-time, hardcore Slackers seem to use agetty these
days, and the setups for, for example, mgetty that I've seen are quite
different in detail.
Oh, one qualification ... technically, ppp is a peer-to-peer connection, not
a client-server process. But in practice, everyone uses the terms client and
server the way you do -- the ppp client makes the phone call and the ppp
server answers the phone (analogous to "terminal server" for a host that
acceptd dialin for shell connections).
