How-to install Slint-64-14.2.1.2 with a Braille display using brltty.

The Slint installers contain the brltty software, allowing blind users
to install then use the system with a Braille device.

The installer is polyglot, here are the available languages:
English (USA)
Dutch
French
German
Greek
Norwegian
Polish
Portuguese (Brazil)
Portuguese (Portugal)
Russian
Spanish (Latin America)
Swedish
Turkish
Ukrainian

Boot off the installation media and when you hear a an arpeggio or a
'beep' you can choose a language, then indicate the settings for your
braille device.

Initially the cursor will be on English (USA). Use the up and arrow keys
to navigate in the languages menu. Don't worry if you selected a wrong
language: you can change it at the beginning of installation.

Press the e key
Press the down arrow three times
Press the End key
Press the space bar
Type the device settings in this format:
<language code> brltty=<driver code>,<device>,<text table>.
For instance to install with a Papenmeier device connected through USB
with a French text table, type:
brltty=pm,usb:,fr_FR
Be aware that the US keyboard map will be in use when typing.
Press Ctrl+X to boot (do not press Enter!)

Within one minute after that the startup messages should be displayed
on the Braille device.

Your settings will be recorded in the installed system in
/etc/brltty.conf, and brltty will be launched at startup by default
with these settings, unless you make the file /etc/rc.d/rc.brltty
non executable, typing:
chmod 0644 /etc/rc.d/rc.brltty

Also, if you plug in a Braille terminal connected through USB when the
system is running, it will work as relevant udev rules should launch a
brltty daemon with the proper driver.

You can consult the Slint website @ https://slint.fr to know more.

A comprehensive manual for brltty is available in English, French and
Portuguese in several formats including plain text (txt) at this URL:
