Hi,
The braille cells part is attached via serial.
Note: about the braille cells part support, we already discussed about it on this list earlier: http://www.openbios.org/pipermail/linuxbios/2006-July/014925.html
Actually, my suggestion would be to forget that we are talking about a braille deviceforthe moment, and to talk aboutthe braille-specific things later. The only thing I am trying to determine sofar is whether the device could run LinuxBIOS ornot. Given that the device can b plugge to both a keyboar and a screen, it makes sense to consider it just as a plain old PC. So the real question at the moment is: can LB be run on this PC or not.
Sébastien.
