Comment 2 by MHameed on 2013-02-23 11:15 What I understood from chatting with Ruslan on irc, is that the display is a model that only supports serial/parrallel connection, so he uses a usb to serial adapter. So what Ruslan is requesting is for the baum driver to have serial port options, just like what we have recently implemented for some of the other drivers. Thanks. |
Comment 3 by ragb on 2013-02-23 11:50 Do you know if the display supports the common baum protocol, as supported by supervario displays and others? Or if brltty supports it, and with what driver?. Maybe Roslan can answer these. If the protocol is the same, it is just a matter of adding port selection, in theory. |
Comment 4 by ruslan (in reply to comment 3) on 2013-02-23 14:48 i don't know whether my display is supported by baum common protocol. |

Comment 6 by jteh on 2013-02-24 00:55 The problem is that there's no single place which documents the common Baum protocol. The documentation Baum provides is slightly different for each type of display, even though it's certainly possible to support them in one driver. I also suspect there is an older Baum protocol which is slightly different. To make matters even more confusing, the BRLTTY Baum driver also supports the other protocols emulated by the Baum displays, which i see no point in supporting in NVDA. Anyway, I can try implementing support for serial ports in the Baum driver when I get a chance. |

Only documentation I can find about it is in German, which for me is the same as noting :).
By looking at brltty's code I can't tell if dm-80 has any custom code or something. That code is not easy to understand with a quick look though.
I recall somehow you own a baum display. is that right? If so it would be easier for you to do that, since at least you can test USB and bluetooth still work as expected. If don't I can try something, but I'm not able to do any testing (if the portuguese Baum dealer acted differently things could by better, but whatever..). Regards, Rui Batista |

Did you select the correct com port in NVDA's Braille Settings dialog? |
The original author of this ticket is now out-of-reach and unfortunately did not respond to @jcsteh's #2948 (comment) either. @jcsteh Do we have resources, contacts or technical information sufficient to work on this issue further? |
We do have contacts at Baum, but without current interest from users, I don't think pursuing this has any practical benefit. I'm closing this for now, but we can reconsider opening discussions with Baum should user interest arise. |
As far as I know, this display is no longer shipped. |

I would like my braile display baum dm80plus to be running directly in NVDA.
it is running but through BRLTTY.
