It depends on the modem. Generally there is a module that is loaded by the kernel, and then it works (or not) just like a hardware modem. You have to find the chipset of your modem. Many are from AT&T. I have a laptop with a SmartLink modem and it loads a module called "slmodem" on startup. It doesn't work well at all and freezes the computer after 5 minutes online. But before I had a TOSHIBA with an AT&T winmodem and had no problems except for the somewhat higher usage of the CPU.
