- 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 serial and USB ports are both supported. The following models are
- recognized:
- * Focus: 44, 70, 84
- * Focus 2: 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 file 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:
