How can I get a modem driver for an obsolete modem? - driver modem vemmax

I have a Motorola SB5100. I uninstalled the modem driver because it was damaged. I tried all the drivers in the Motorola web site, but none of them works. It may be because I have bit Windows 7 (32), but I doubt it. Where can I a get that works that you use for the Internet on my computer?
