Lucent Winmodem Under RH7.2

I have a Lucent winmodem under Redhat 7.2, Im pretty sure its ISA but im not sure...if you need to know Tell me and I can check. I was wondering how to get it up and working. I have installed the binary files from a link followed in the "Installing winmodems under RH8 and Rh9" Everything went smoothly and no errors occured. But then when I tried to set the the account and dial my modem was not detected. Any ideas why? and how to fix it? If you need to know anything else tell me.
