[quoted lines by Aura Kelloniemi on 2019/05/14 at 16:52 +0300] >It would be quite a coincidence, if they had the same cells broken.
Yes! :-) >Also, most often the whole cell is not defunct, but some particular dots are. >BRLTTY could take this into account and still use the broken cell if the >broken dots are not needed in the braille pattern that is to be written to the >cell. This implies that brltty would sometimes use, and at other times not use, such a cell. This'd cause the output from that cell onward to shift back and forth, which, in my opinion, would become very confusing. I think it'd be far better for brltty to simply skip over such a cell so that the user never has to guess at what's going on. >And what should BRLTTY write to the cells which the user has reported as >non-working? Should they be left empty (which might lead to confusion about >whitespaces) or should all (working) dots be raised up? Maybe this would be >configurable, because marking defunct cells already requires configuration. I think it should be configurable as each user will prefer something different, and also because it may well depend on how a given cell is deffective. >Some devices probably allow their serial number to be queried, which at least >in theory could be used to choose the correct list without user intervention. That's an excellent idea! >Currently I'm lucky not to have a single broken dot in my display, but I have >another issue which could potentially be solved by this feature. When the >battery of my Focus Blue is low (<=10%), the firmware writes a status >indicator at the righthand side of my display. This indicator cannot be >disabled and it is shown all the time.

But I would >prefer to have those cells be filled with the pattern ⣿ (all dots up). This >would be much less confusing than having garbled text at the end of each >braille window. In your case, I'd suggest listing those cells as deffective and to be filled with just dots 1-6. That way, you still get your indicator. -- I believe the Bible to be the very Word of God: http://Mielke.cc/bible/ Dave Mielke | 2213 Fox Crescent | WebHome: http://Mielke.cc/ EMail: [email protected] | Ottawa, Ontario | Twitter: @Dave_Mielke Phone: +1 613 726 0014 | Canada K2A 1H7 | _______________________________________________ This message was sent via the BRLTTY mailing list.
