Got it.
I can't read source codes, ... well, not very well.... Okay, will check and get back. I have posted an email to the Debian forum.
I have checked the aptitude information for wvdial and found an email-Id for the creator of wvdial, which is wvdial\-list@lists.nit.ca, but it bounced back. How do you interpret that email-Id.? I also posted to wvstreams-devel@googlegroups.com.
Let's see what transpires from our endeavours.
