- Kernel Driver for the Tieman Voyager Braille Display (USB)
- Authors:

- Version 0.8, April 2002
- The brlvger driver supports a Braille display (aka Braille terminal)
- model Voyager from Tieman.
- The driver has been in heavy use for about six months now (as of April
- 2002) by a very few users (about 3-4), who say it has worked very well
- for them.
- We have tested it with a Voyager 44, but it should also support
- the Voyager 70.
- This driver implements a character device which allows userspace programs
- access to the braille displays raw functions. You still need a userspace
- program to perform the screen-review functions and control the
- display. Get BRLTTY from http://mielke.cc/brltty/ (version 2.99.8 or
- later). It has a Voyager driver which interfaces with this kernel driver.
- The interface is through a character device, major 180, minor 128, called
- "brlvger" under devfs.
- Many thanks to the Tieman people: Corand van Strien, Ivar Illing, Daphne
- Vogelaar and Ingrid Vogel. They provided us with a Braille display (as
- well as programming information) so that we could write this driver. They
- replaced the display when it broke and they answered our technical
- questions. It is very motivating when companies take an interest in such
- projects and are so supportive.
- Thanks to Andor Demarteau <ademarte@students.cs.uu.nl> who got this whole
- project started and beta-tested all our early buggy attempts.
