Bug#500441: Please document the braille support in the release notes
Hello Luk,
here is my suggestion for the documentation of the Braille support in
the Debian installer.
---BEGIN
Install Debian with a braille display
You can install Debian Gnu/Linux 5.0 (Lenny) with a braille display. The
braille display must be connected to a USB or a serial port. If your
braille display is connected to a USB port and the American braille
table is supposed to be used, you can press Enter in the boot menu. The
screen reader BrlTTY is standardized to search for braille displays at
the USB port and uses the American Braille table. If the braille display
is connected to a serial port or if you want to use a different braille
table, you have to press the tab key in the boot menu first. Then, you
can configure the screen reader BrlTTY with the kernel parameter brltty.
For the parameter, the following syntax is valid:
brltty=driver,device,table
All operands are optional.
Driver = The driver for the employed braille display. Here, you must
enter either a code consisting of two letters or the word auto. If this
argument is not entered, the automated recognition is activated by
default.
Device = The device can be entered as relative to /dev/ as well as an
absolute specification.
Table = Defines the braille table for the desired language. By default,
the US table is employed.
Examples:
brltty=ht,ttyS0,de
The Handy Tech Driver is used. The braille display is connected to Com1.
The German braille table is used.
brltty=,,de
Here, only the German braille table is specified. Therefore, BrlTTY will
try to find a braille display at a USB port.
---END
In the appendix of the release notes, the list of the available drivers
and Braille tables should be found. Unfortunately, I do not know, which
adjustments for the use in the Debian installer have been made. Maybe
Maintainer Mario Lang can help out here.
Hopefully, my suggestions are useful to you.
Simon
