I committed your patches from last week yesterday.

Yeah, it's probably a good idea. Overriding the whole Enable() is a
bit too much work if you only need to use a different init string.
I'll have that later today.
Don't know if this will help...
I patched the version that comes with Ubuntu Intrepid (0.7~~svn20081018t105859-0ubuntu1) and replaced all ATZ commands with AT&F. This time things got further, here is the output from the debug trace....

This looks much more promising, but there still seems to be an issue when it tries to dial.
Here is the trace of my wvdial exchange that works...
