SAM Driver for Blazie Engineering Braille Lite

This is a fully functional SAM driver for use with the Blazie Engineering Braille Lite. This includes 18, 20 (Millennium) and 40 cell models.

The driver works in both Windows 95 and Windows NT.

To use this driver, the Braille Lite must be set to Speech Box mode with the following serial port parameters:

9600 baud, no parity, 8 data bits, 1 stop bit, full duplex, hardware handshake.

To set these parameters, go into the Status Menu in the Braille Lite by pressing dots 34 chord. To skip directly to the baud rate parameter, press B (dots 12).

To Enter Speech Box mode, press dot 345 chord followed by dots 1234 chord.
All keys on the Braille Lite then go to the screen reader and are not processed by the Braille Lite (except dot 345 chord).

In order to return your Braille Lite to normal operation, exit Speech Box mode by pressing dots 345 chord followed by dots 1234 chord again.

Consult the Braille Lite manual for further details on all these commands.
