[BRLTTY] Support for 'dead' or broken cells?

[Peter Parente]

Hi all,

The way it's implemented in LSR is the following:

1) Everything to the right of a broken cell is right shifted by the
number of broken cells to the left of it.
2) The touch cursors are offset by the same amount.
3) To the LSR script writer, the display length is reported as number
of physical cells minus number of broken cells. (The script writer
doesn't need to deal with which cells are actually dead.)
4) The user configures dead cells in LSR using a fixed length text box
matching the length of the display and containing a string having 0s
and 1s in it. The user presses the touch cursor key above a dead cell
to move the caret to that location in the text box. Entering a 0 there
disables the cell it while entering a 1 enables it. (There's probably
a prettier way to do configuration, but this is the simplest solution
that came to mind at the time.)

I would be happy to see this feature implemented directly in BrlTTY.
