I do not think that it is legal to use a driver from Dell without hardware sold by Dell. In my opinion the driver was for their customers only and not for anybody who does not want to support developers but use their products.

You could consider to buy a new modem for the serial port, but most modern computers only have USB ports. Thus most people would also have to buy an adaptor that converts the USB port into a serial port.

I think that your issue is solved because you can Knoppix V7.0.4 make work with your dial-up modem although you have to use additional software. It is not necessary to download the DVD version of Knoppix 7.0.4.
Thanks again. Yeah someone told me just to buy a serial modem with an USB adapter. However, they are old and hard to find these days. What is nice about USB modems is that they supply power through USB. I wasn't expecting these USB modems to be Winmodems and so difficult to deal without Windows OSes. Also, I wasn't expecting its driver not to be free to use for full speed!
