[BRLTTY] problem with keyboard braille display

[stéphane lapique]

Hello,
I am using brltty with nvda on 64 bit windows.
I specified with the brltty configurator the name of my braille range
and the communication port.
My visiobraille braille terminal does display the information from the
pc on the touch screen display, but the braille keyboard of my
terminal is not taken
into account.
Could you enlighten me on the specific configuration to bring to
brltty to solve this problem?
Thank you.
Best regard
