[BRLTTY] Terminal Type for Braille Edge connected via BRLTTY

[Kevin Fjelsted]

Quoting Dave Mielke<<<<no. His problem is that he's trying to will the device to work the way he'd 
like it to. He's decided that they should function like keyboard arrow keys, 
and wondering why they don't. The answer is that they don't work like keyboard 
arrow keys because that isn't their function. Their function is to passively 
move the braille display around the screen without touching the cursor.

This is what we need to do.
 Interpret the command that the Braille Edge is sending when either the uparrow or down arrow is being pressed. To be clear about which keys  I am referencing, these would be the two vertically spaced keys that are mirrored at the left and right side of the display at either end of the row of cursor routing buttons.
We need to send these corresponding up and down commands that the Braille display is sending when these keys are pressed to a program that will then send one unique line of text to the Braille display based on whether the up or down key is pressed.
Can anyone advise on what resources are available, and where the documentation is for such a resource that would permit us to do this? I looked briefly for documentation on BRLTTYAPI and although I found some examples of programs that call it, it would be helpful if there was some overall documentation.
