In linux kernel since version 2.6.26 (release Date: 2008-07-13)  
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.
