The Intel SatisFAXtion 400 Internal Modem does not work with Windows NT. The SatisFAXtion 400 is software-configurable only and requires MS-DOS-based drivers to initialize correctly.

Because the modem has no hardware-configurable switches, it requires that a configuration file and a device driver be loaded when the system is booted. Under an MS-DOS system, these are loaded in the CONFIG.SYS and AUTOEXEC.BAT files.

In the CONFIG.SYS file, there is usually an entry similar to the following:

   device=c:\fax\satisfax.sys /ioaddr=xxx

In the AUTOEXEC.BAT file, there is usually the following entry:


Because the device driver attempts to communicate with the hardware directly, it does not work under Windows NT.


   The Intel SatisFAXtion 400e external modem does not have this problem.
   There are hardware switches on the modem that allow it to be configured,
   so the modem should work correctly with Windows NT.

   Intel has release a Class 1 Windows NT driver for the SatisFAXtion 400i
   modem. This driver works under Windows NT versions 3.1 and 3.5 and is
   available from the Intel (GO:INTEL) forum of CompuServe. Filename:
