er0k: say exact model.

I remember on my RedHat 7.2 later on 7.3 I had to recompile my kernel manually to force my modem work. With default kernel compiled at installation these drivers don't work I think.

Warning! Some 127a:1025/2005 modems might be HCF not HSF.

And get newer drivers at http://www.mbsi.ca/cnxtlindrv/. And you might need a tool to know what model you have. Get it here: http://www.mbsi.ca/cnxtlindrv/modemident.html
