A "Winmodem" is sort of a half a modem.
Wher much of the hardware stuff is replaced by software drivers.
While a standard modem, you can plug it in to a COM or USB port,
and just send raw commands to it, and it works fine.
A win modem needs extra drivers to enterpitate thes commands and make the lamemodem, err. Windmodem understand them.
I dont know of a Distro that supports winmodems out of the box.
So it can be abit tricky to get them working.
However not imposible.
Personaly I have not gotten a winmodem to actualy work.
But thats cus I have only encountered them in Stationary PCs and then simply desided its not worth is, and get a NIC and get a Broadband connection insted.
If you realy dont have any other choise than to get the Winmodem working.
