Which modems are supported by Knoppix?

[tdjokic]

all i know is that
US Robotics 56K PCI Faxmodem model 5660A and
Conexant HSFi V90 V92 56K PCI Modem
dont work right out of the box. So maybe they just have to be custom configured to work with Knoppix, but i'm new to Linux so I have no clue what to do, and so far i'm not getting any help

Some Linux distribution have integrated drivers for (some) winmodems: Mepis, Kanotix (younger brother of Knoppix), ALT Compact (http://www.altlinux.com/), Kurumin, but Knoppix has not. Your both modems are winmodems and this is good site to start with: http://linmodems.technion.ac.il/
