What is the primary function of the brltty program?

The brltty program's primary function is to provide Braille display support, which is essential for users who are visually impaired. It acts as a background service that allows text output from the console to be displayed on Braille terminals, enhancing accessibility for individuals who rely on Braille for reading.

The program facilitates seamless communication between the operating system and various Braille devices, enabling users to interact with the system and read on-screen content in a tactile format. This functionality is critical in making Linux environments more inclusive and providing equal access to information for all users.

While user account management, audio-to-text conversion, and file system management are important in their own right, they do not relate to the primary goal of brltty, which focuses specifically on enhancing accessibility through Braille support.
