[BRLTTY] Getting new braillex model to work

[Peter Lundblad]

Hi,

I've got a new Braillex EL display that I'm trying
to make working with brltty.  It identifies itself as model 91, which
is not listed among the current configurations.  I copied on
PM_TERMINAL entry for a similar display and tried to change it, but
the problem is that even though I set the number of status cells to 20, the
text starts showing up on the vertical display.  Is anyone here
familiar with programming these kinds of displays so we could try to
debug this together?

The display is an 80 character display with a vertical line of 20
cells. It has an easy access bar and one button on each side of the
display.  There are two routing keys on each cells.  I'm happy to
provide any other information that might be helpful and to test/hack
according to any instructions;)

Thanks in advance,
//Peter, who's not a hardware driver hacker, btw...
