Hi, I found this at www2.driverguide.com/uploads/uploads11/15310.html but I'm re-submitting it so it can be indexed under alternate keywords. This driver worked for my Pacific Image Communications 56K SuperVoice PCI-based internal modem under Windows XP Home Edition. This modem is otherwise known as the Ambient HaM Data Fax Voice modem.
To install this driver in Windows XP or 2000, right-click on My Computer and select "Properties." Click on the "Hardware" tab, and click on "Device Manager." Select "Simple PCI Controller," right-click to get Properties, and click "Update Driver." Tell XP to search on the unzipped directory.
