I give up.  I've tried everything I know how to do....

-Read multiple How-To's
-Changed modems, no difference.
-Changed cables, no difference.
-Changed modem and cable, no difference.
-Installed old version of Slack that worked previously on the same system, no 
difference.
-Reinstalled numerous times, no difference.
-Tried installing without NIC in, no difference.
-Tried different dialing methods, no difference.

None of the above methods have allowed me to connect a desktop machine 
running Slackware to the internet.

Should never be this hard.

I give up.....
