[BRLTTY] Braillex EL 66S problem

[Delaunay Christophe]

Hi all,

I recently acquired e new braillex el 66s Braille display from
Papenmeier.

I successfully installed it on a windows-based PC so I can be sure that
from a hardware point of view, it works correctly.

Then, I connected it to the linux PC and started brltty.

Brltty displays normally but I can't navigate through the screen. It
seems like all the functions from the so-called Easy Access Bar of my
device are unmapped.

How can I check this please? I tried to enter learn mode. But, in this
mode, only commands which are mapped are shown. For instance, when I
press left switch backwards, brltty displays "home" and its description.
When I press right switch forwards, brltty displays "help" and its
description. But when I press both left switch backwards and right
switch forwards, brltty does not display anything since this command is
not mapped.
Now, when I move the EAB, how can I know that brltty received something
and what it received if possible?

Many thanks. Have a nice day. ChD
