Yours is in the HSF family (it's a "softmodem", or "winmodem" as they 
are often called - relies on software provided as part of Windows to 
make it work in normal circumstances).

In my experience, often the simplest option is to simply buy a 
second-hand external modem which should work "out of the box". But best 
of luck anyway.
