Re: [ros-dev] no replies about making reactos accessible for the blind

I'm not saying it isn't possible to support the hardware, just I have not seen any
pre-boot environment that the installer might need to communicate with attempt to provide
this support, so it is also available to whatever gets installed, after reboot. The
installer may be fine using only 6-dot combinations, but I'd consider it likely some
varieties of applications will assume all 8 dots may be input or output over the single
channels most compilers support.

Braille will not be output by GPU, it will be output by CPU onto either
USB or serial Braille bumper. Two different output channels may use two
different codepages. If they were somewhat dependent as in multi-monitor
situation, you would need to drive both via GPU. However they are
independent output channels, which just happen to share contents.
Commonly used Braille is a six dot encoding and most letters and numbers
are encoded by this encoding. Eight dot encoding is used for music and
mathematical notations.
