I'm trying to fix an employee's laptop modem and have hit a brick wall...

The modem: Compaq Pressario 56K-DF

When I go into "Phone and Modem Options" from the Control Panel, it lists this modem under the "Modems" tab. In the "Attached To" collumn, it says "not functional". No further explanation is given, and evidently since it is not functional, you cannot get into its properties or do anything with it.

Any clue as to what to do, or is this modem just R.I.P.?
