application can prevent WFS from working. Uninstalling it won't necessarily
remove the settings it wrote to the modem.

I'm having a very similar problem sending faxes using Vista 32-bit Ultimate
Windows Fax and Scan. I have a Zoom 4300A Bluetooth Modem which is Class 1
fax and have checked the Zoom Technologies Web site where it says it is Vista
compatible. (I was unable to find on the Microsoft VHCL)
The modem is detected by Vista and it sees it as a fax and I can dial out
etc. When I try to send a fax it dials the number, tries to connect, the
answering fax machine starts handshaking, and then I get "An unknown error
has occurred". I purchased the Zoom modem after the same error happened
which my U.S. Robotics Win INT modem. I was previously able to send faxes
with no problems on Windows XP.
I have wiped my machine and tried a fresh install of Vista, ensuring all
drivers are the most up to date but still no joy...Any suggestions?
