Is it possible to start work on native driver for Optelec displays such as BC6 series?

Here are some benefits:

  • many users use these displays (BC640/680, BC640 Comfort (USB and also emulate them with protocol converter attached to Alva Satellite or Tieman Voyager displays.
  • It would be possible to use advanced braille features which are coming to NVDA.

Unfortunately I don't have enough skills to develop it but if I can help you on the other way, please tell me.

Thanks,

CC @dkager, who also has such a display and has some decent programming skills. I will see whether I could get an old device myself.

I have to note though, that it would be very helpful to have the data protocol for these displays, especially to implement the converter and Comfort part.

Hi,

shell it help you if I sent you a protocol converter via postal service or DHL? my display is currently on a maintenance and repairment so I do not need it now.
If you guide or tech me I will also be glad to send you other materials to successfully develop a native driver for BC6 series.

regards, Jožef

The most important thing is the protocol, so if you could assist in getting hold of that, that would be awesome.

I might have time to work on this around christmas, but I don't have a protocol to work with, only a BC640, without the comfort part. Unless I have a protocol document, I probably have to work with what BRLTTY and some device monitoring tools will tell me.

I've had contact with @jcsteh and might be able to start with a native driver very shortly. @gregjozk, your testing would of course be greatly appreciated. I will start posting try builds here whenever they are available, probably within the first or second week of January.
