You seem to be  attempting to do a terminal login before envoking
ppp, and I suspect that you don't need to go through this process.
However, if you do then I would recommend doing a "manual" dialup
using minicom to see the exact sequence of strings and replies that
are needed to get it working.

That is all I would have in that file.  Put the rest of the options
into a file in the /etc/ppp/peers/ directory and use them with the
"call" option on the command line.  (See the man page).  By doing it
like this, you can have multiple configuration files (eg, for
multiple ISPs) and use any of them whenever you want.  I posted
examples of this only recently in this list when explaining how to
configure a dial-in ppp server.

Take care... if you are having hassles then start with the basics
using default options (ie, as few as possible specified) and only
add what you really need from there.  eg, I'm not sure why you want
to specify the asyncmap or lcp-max-configure parameters.

I've been using this as a "generic" chat script for several ISPs and
it seems to work well.  It is a pity that you need to chat your way
through a terminal login (are you sure that you really need to do it
like that?)

ABORT 'NO DIALTONE'
ABORT RING
ABORT BUSY
ABORT 'NO CARRIER'
ABORT 'NO ANSWER'
ABORT 'DELAY NUMBER WAIT'
REPORT CONNECT
TIMEOUT 60
'' ATZ
OK \dATL3
OK \dATX4W2
# SAY "Dialing \T"
OK \dATDT\T
CONNECT

That's bad, anyone can read your passwords, so do this:

	chmod 600 /etc/ppp/pap-secrets

Hmm, "serial line is looped back" is a way of saying that it is
"talking to itself".  Authentication probably failed.

Redhat 7.2 comes with vwdial (the redhat ppp dialer is a gui
interface for it).  It has always worked for me to quickly set
things up, give it a try.
