I have an internal modem, winmodem to be exact, but what I really want to know is: If I buy an external modem i don't want to waste my money and have knoppix not find it. I guess i could just bring my copy of knoppix to a computer parts store and test it then and there, but they might not be to impressed with that. Also I deal through bell sympatico and they supply high speed modems will knoppix configure them. I would rather use a linux operating system but thus far modems are forcing me back to windows.
