I'm using a Red Hat 9
Modem U.S.Robotics 56K Message Modem.
Installation Ok,
the modem answer, i can reach the ISP, the remote modem answer.
I used this string:
/usr/sbin/pppd /dev/ttyS0 57600 debug user myuser@tiscali.it connect "/usr/sbin/chat -v -t60 '' ATZ3 OK ATD0,,7023456789 ARQ ''"
the debug log says:
Jan 11 22:31:14 CFabioHost pppd[12311]: Serial connection established.
Jan 11 22:31:14 CFabioHost pppd[12311]: using channel 11

Jan 11 22:31:45 CFabioHost pppd[12311]: Exit.
If I go to check the chars that the two modems exchanged,
I found:
(I get it with pppdump on the file generated with the record option of pppd)

It seems that pppd does not recognize the return string from ISP.
I've tried to find something about this problem in the howto and some other internet connection instruction,
but I have found anything.
these are the files I've used:
#/etc/ppp/options
#
lock
crtscts
noipdefault
noauth
defaultroute
receive-all
record /home/cfabio/pppdrecord
#/etc/resolv.conf
domain tiscali.it
nameserver 195.130.224.18
#/etc/ppp/pap-secrets
# Secrets for autentication using PAP
# client server secret IP addresses
"myuser@tiscali.it" * "mypassword"
I could made some mess in the hosts file, but I think that it can't be the problem at this stage of the connection.

but anyway I can't get the authentication with script with chat, and also wvdial does not work.
thanks to all
