Accessibility handles all special kinds of hardware devices or software adapters which help people with disabilities (e.g. blindness) to use computers. That includes braille devices, speech synthesis, keyboard remapping, etc. Say Y here to get to see options for accessibility. This option alone does not add any kernel code. If you say N, all options in this submenu will be skipped and disabled.
If unsure, say N.if ACCESSIBILITYconfig A11Y_BRAILLE_CONSOLE bool "Console on braille device" depends on VT depends on SERIAL_CORE_CONSOLE ---help--- Enables console output on a braille device connected to a 8250 serial port. For now only the VisioBraille device is supported. To actually enable it, you need to pass option console=brl,ttyS0 to the kernel. Options are the same as for serial console. If unsure, say N.endif # ACCESSIBILITY
