I'm allowing this message simply because there may be an add-on, probably home grown and unvetted, that will support what I have to believe is a Braille display named Braille Bar.  Passing along this information on the group is just fine, as is mention of any simple technique/setting in an out-of-support version of NVDA that might "magically unlock communication" with this display.

If there are to be deep dives into Windows 7 or ancient versions of NVDA, those need to occur off list.  Use the Reply to Sender link in the original message to correspond privately if needed.

The depths of denial one can be pushed to by outside forces of disapproval can make you not even recognize yourself to yourself.
