3com 3cxm756 pc modem

I bought this modem on ebay for $4.00 and kppp found and configured it immediately!! I have tried a half dozen linux distros on this box (Presario 2100 laptop, 40gb hd, winxp/linux dual boot) and none worked. This card was found right away on kppp and the rest was just entering numbers. Give it a try...Jonn
