[BRLTTY] Contracted braille typing related question

[Hammer Attila]

Dear list,

With hungarian language, both computer braille, grade 1 and grade 2 
already good supported in Liblouis. In console I often use with Brltty 
with contracted Braille mode, simple I pasted the hu-hu-g1.ctb table 
with following way the brltty.conf, very old time I think John Boyer 
suggested this change in this list:
contraction-table	louis:/usr/share/liblouis/tables/hu-hu-g1.ctb

If I remember right, me only need enable the contracted braille support 
the Brltty preferences menu the proper place, but I am not full sure this.

My question:
This way if an user have a braille display with have a perkins style 
phisical braille keyboard, not possible support BRLTTY the braille 
typing? So, if this is possible we would like use Liblouis the braille 
input back-translation, because hungarian Liblouis braille tables 
already supports braille input rules too, and in grade 1 level the 
back-translation quality is very good fortunatelly in hungarian language 
(I am the official hungarian maintainer with Liblouis hungarian tables).

If this is possible, to supports BRLTTY the contracted braille input and 
native contracted braille presenting, I not would like develop a total 
new contraction table for BRLTTY, if I remember right, the conversion 
from the actual Liblouis table is impossible.
So, if this is possible, I would like maintaining one place the 
contracted braille table. :-):-)
Sorry if my english not always right.
