hayes modem; loopback detected; connection quits
 

Hello!
I have a Hayes ecternal 56k + fax modem, model 5674US on ttyS1 (com 2 in Winxp).I'm using Ubuntu "Breezy". Every time I start pon from a terminal, I get the following messages in my /var/log/syslog:

michelle@mainframe:~$ pon
michelle@mainframe:~$ sudo tail -f /var/log/syslog

I've added myself as a user to dip and dialup groups; edited /etc/ppp/ all files in dir with correct login info; I've edited /usr/share/ppp all files in dir with login info that wasn't there at all; Ive created and edited wvdial.conf with correct info, as well as the chatscripts and provider scripts. What can I do now, beside scrub linux and go back to windoze (ugh!!), because I can't get online after 2 months?
Any help will be greatly appreciated. Thanks in advance!
