The best signal to use is TERM.

>When I currently use `killall brltty`, 

"killall -TERM -x brltty" would work, but there's a better way. One reason you 
should use a better way is because using killall terminates every single 
brltty, which may not be what you want if you're rujnning more than one of 
them.

Another way would be to figure out the correct pid, then then do:

   kill -TERM pid

There are command line options to make this a lot easier. Use -P (uppercase) 
when starting brltty so that it'll create a .pid file:

   brltty -P /run/brltty.pid

Then, to terminate brltty, specify the same pid file along with -C (uppercase):

   brltty -P /run/brltty.pid -C

This, in fact, is how brltty's systemd unit works.
