When you are using a Digicom Systems (DSI) Scout Plus fax/modem, fax transmissions fail.

Back to the top

DSI Scout Plus fax/modems fail to negotiate with some brands of fax/modems and fax machines because of the manner in which flow control is implemented on this fax/modem.

For example, it has been reported that the DSI Scout Plus fax/modem cannot negotiate with the following equipment:

•	Compaq 2411
•	Compaq 224ATF

To use the DSI Scout Plus fax/modem successfully with Windows 95, you must change the flow control method. To do so, change the SetupCommand key to "ATS7=255&D3*F2" (without quotations marks) in the following registry entry:

    HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\At Work Fax\Local Modems\TAPIxxxxx
				

After you make this change, restart Microsoft Exchange.

For information about how to edit the registry, view the Changing Keys And Values online Help topic in Registry Editor (Regedit.exe). Note that you should make a backup copy of the registry files (System.dat and User.dat) before you edit the registry.

WARNING: Using Registry Editor incorrectly can cause serious problems that may require you to reinstall Windows 95. Microsoft cannot guarantee that problems resulting from the incorrect use of Registry Editor can be solved. Use Registry Editor at your own risk.
