It would be quite a coincidence, if they had the same cells broken. 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. But... dots can be defunct in (at least) two ways: most often they don't rise, but sometimes they don't go down, but instead stay completely (or halfway) up all the time. This would increase complexity, if BRLTTY would take into account specific dots instead of just whole cells. 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. Suggestion: maybe add broken dots lists to configuration file items. User could then choose from the configured lists in the preferences menu, or choose no list (similarly to language profiles). 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. 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. The firmware uses dots 7 and 8 in this indicator (which is 1-5 cells wide, depending on the battery status). Unfortunately I use a braille table which extensively uses dots 7 and 8, so the battery status indicator completely garbles all characters in the last five cells. Currently I work around this issue by setting Window overlap to the width of the status indicator whenever this problem appears. 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. However, even though some other people with Focus displays may suffer from this same problem, I think it is a rather specific issue and should not guide development decisions very much. -- Aura _______________________________________________ This message was sent via the BRLTTY mailing list.
