Start by locating the dsmlink.prefs file. This file can be found in the DSMLink main program directory. Unless you specified something different at install time, this would normally be:

C:\Program Files\DSMLink

Edit the file with Notepad or some other basic text editor. Be sure that DSMLink is not running while you edit this file. Once you save the file, run DSMLink again to see the effects.

Add the following line to your dsmlink.prefs file. You can add this line anywhere in the file.
