I'm currently writing a program for a project.
It is for a braille reading system where I have a braille display connected via USB that is controlled by a program called brltty.
One of the requirements for this project is to have the ability to connect more than one braille display although only let the master display have control of the system.
I thought the easiest way to do this was, rather than having to send commands to every instance of brltty in my program, I could just mirror what is output to the main USB, to each USB port.
Is this possible?
