[BRLTTY] Understanding brltty on a linux machine

[Pranav Lal]

Hi,

Sorry, I am getting seriously mixed up. 

I can press keys on the braille display and things do change. 

When I did the test, I was in a text terminal. 

However, when I write python code and run the scripts, I get speech output from the linux server but no braille.

Are you using a graphical window such as mate-terminal?  Are you saying pressing keys on the Braille display doesn't work?
