[BRLTTY] introduction and a problem

[lutz kaiser]

Hello list,

i'm Lutz 42 years old and use brltty since more than 5 years.
my system:
debian unstable , Combibraille 40 connected via usb2serial (ftisio)

Since updating brltty to version 4.2 all went allright.

But now i have the problem, that the display did n't work as it used before.

Two "ways" to start it:

1: start a second instance of brltty, then the Display works but very 
slow reaction;

2. starting brltty the normal way and
cat .../brltty/Drivers/braille/combibraille/* >/dev/ttyUSB0
then it works normal

sorry, there ist no exact file braille.c or braille.h which causes the 
display to start.. so i have to send all to it.

I also installed the developerversion via svn checkout, the same result.

Tank you for reading,  and hope it helps to solve the issue
Lutz
