This directory contains the BRLTTY driver for the Focus and PAC Mate braille
|
|
displays from Freedom Scientific [http://www.freedomscientific.com]. It has
|
|
been implemented, and is being maintained, by Dave Mielke <dave@mielke.cc>.
|
|
|
|
The most important single command is the one to access the help screen. On the
|
|
PAC Mate display this is the key just to the right of the center marker (also
|
|
referred to as HK5 below). On the Focus, this is chord H (Space+Dots125).
|
|
|
|
Serial, USB, and Bluetooth are all supported. The following models are
|
|
recognized:
|
|
* Focus 1: 44, 70, 84
|
|
* Focus 2: 40, 80
|
|
* Focus Blue: 14, 40, 80
|
|
* PAC Mate: 20, 40
|
|
|
|
If an unrecognized model is connected then the driver makes an attempt to
|
|
determine its size and to provide generic capabilities.
|
|
|
|
The upper row of routing buttons on the PAC Mate are a set of hot keys. They
|
|
provide quick access to various braille display functions and options (see the
|
|
help screen for what they actually do). There are three markers at the back of
|
|
the display's top surface, i.e. just behind the routing buttons, which help you
|
|
locate and distinguish each hot key. The keys immediately below the left and
|
|
right markers are the left and right GDF keys. Between them are eight keys ...
|
|
four on each side of the center marker. The buttons between the left GDF key
|
|
and the center marker are named (from left to right) HK1, HK2, HK3, and HK4;
|
|
those between the center marker and the right GDF key are named (from left to
|
|
right) HK5, HK6, HK7, and HK8. Any button to the left of the left GDF key acts
|
|
as the left advance key, and any button to the right of the right GDF key acts
|
|
as the right advance key. The following drawing depicts this layout visually:
