TJT1234's instructions work. For other versions of JAWS, probably the only thing that might be different is the version number of Eloquence, it might not be 6.1, but that should be obvious.
I tried setting inflection to 100 and didn't like it so I set it back to 30. Later I'll try other values to see if there's one I like better than the default.
For those who have Code Factory's Eloquence for Windows, this should work as well, you'll find the eci.ini file at c:\Program Files\Code Factory\Eloquence for Windows.
