Coincidentally, just after I read this, I spotted this announcement :
-----
BRLTTY - Access software for Unix for a blind person
using a soft Braille terminal
Version 2.0, July 1998
Copyright (C) 1995-1998 by The BRLTTY Team, All rights reserved.
Nicolas Pitre <nico@cam.org>
Stéphane Doyon <s.doyon@videotron.ca>
Nikhil Nair <nn201@cus.cam.ac.uk>
(and others)

[snip]
BRLTTY attempts to fill this gap. It runs as a daemon, possibly started
at boot-time, and allows a soft Braille user to access text mode
applications directly from the Linux's virtual consoles. Since BRLTTY is
written as a daemon, it should allow a user a completely free choice of
application and development tools.
CURRENTLY SUPPORTED HARDWARE
============================
BRLTTY requires Linux kernel 1.1.92 or later (for `/dev/vcsa0'). It has
been tested on
The following Braille displays are supported (serial communication
only):
- Tieman B.V.: CombiBraille 25/45/85;
- Alva B.V.: ABT3xx series;
- Telesensory Systems Inc.: PowerBraille 40 / 65/81;
Navigator 20/40/80 (latest firmware version only?).
- Papenmeier Screen 2D Terminal
- EuroBraille family of displays (tested only on ClioBraille 40)
Where to find it
================
BRLTTY version 2.0 can be downloaded from the following FTP sites:
sunsite.unc.edu /pub/Linux/system/access/brltty-2.0.tar.gz
ftp.leb.net /pub/blinux/brltty-2.0.tar.gz
If it's not there, it may still be in the incoming directory.
It is also possible to download the package from the home page at:

Unfortunately it's only for Linux so far, but looks like a starting
point?
Sam.
