I've never heard of such a thing. I'm not sure how that one would exactly work, short of a signal intended to be received and translated into something a Braille display hooked up to the rig could decode. I'd be interested to see if it were actually doable, and I say this as a Braille reader. Yes, I'm outing myself not only as a geeklady, but a blind geeklady!
Ask Mark whose username I currently forget how to spell (sorry mate). He'll verify I'm not lying; he's met and DX'd with me. I really am blind.
