I have been doing some early work with braille terminal display on a Mac here is what I have found so far using a BrailleNote BT.
The BrailleNote BT uses serial communications so you will need a USB to serial device. I am able to trap and display all the spoken prompts and information from the BrailleNote on the Mac using Zterm or simply opening up the /dev device. I can send, with limited success, text to the BrailleNote in braille terminal mode. I have a support request in to Humanware to get the technical specification for communicating with the braille terminal. I need to find out how to trap the text strings that VoiceOver reads so they can be sent out to the BrailleNote. The process or something similar should work for most other braille displays including newer USB devices. Anyone who wants to send me one is welcome to do so. :) Greg Kearney
