Requirements

BRLTTY has been tested on an incredible range of computers, Linux distributions, and kernel versions. It runs with a good response time on a machine as pitiful as a 386SX20 with 4MB RAM. It has been used on laptops, desktop PCs, a DEC Alpha running Alpha Linux, and a few Linux-based PDAs.

Kernel 1.1.92 or newer is required. 2.0.x kernels work fine.

BRLTTY does not depend on a specific distribution of Linux. It has been installed on top of Debian, Knoppix, Mandrake, Red Hat, SlackWare, and SuSE. It has also been used in the barest of boot/root disk sets.

BRLTTY needs to run as root in order to gain access to some of the console functions. It runs as a daemon, and does not need to be set-uid or set-gid.


Restrictions

BRLTTY cannot be used on its own within graphical environments like X-Windows and svgalib. Screen readers for these environments can, however, communicate with BRLTTY via its BrlAPI interface. Orca is an example of just such a screen reader which uses BRLTTY via BrlAPI in order to make the X-Windows environment accessible to braille users.
