[BRLTTY] locating the BRLTTY configuration file

[Michael Weaver]

I can't seem to be able to locate my BRLTTY configuration file in
my /etc directory?
Where is the file to be found because at the moment I am having to
launch BRLTTY the long way with sudo brltty -b bn -d /dev/ttyUSB0 -t en
for each time I want Braille output in Ubuntu Lucid?
I use I think it is BRLTTY 4.1
