OK.. this works...
I found that the diald.conf file in /etc pointed to a /etc/sysconfig/etwork-scripts/chat-ppp0 file
I looked at this file and it mirrored what I was seeing in the messages logfile when the dialup was happening.
I modifie the phone number to include the *70, and wham!! it worked!!
caution:
there is a note on this file that says you should not modify this file, but instead modify a template file. I followed the directory it said, but in the custom templates directory it was empty. So I went to templates/etc/sysconfig/netowrk-scripts/chat-ppp0/30dialup
I modified it instead to read:
'OK' 'ATD{ *70,$DialupPhoneNumber }'
I don't know if it will stick, but it seems to be at least working for the moment.
Thanks for all the suggestions
