[BRLTTY] Startup problem with brltty under Ubuntu together withOrca

[Hermann]

Hello Dave,
sorry, but nothing works.
update-rc.d brltty start 25 S
doesn't exist.
I removed all symlinks and then entered
update-rc.d brltty defaults
which caused the system to add several links to /etc/rcx.d directories,
where "x" means numbers between 0 and 6. The links were named S20brltty and
K20brltty. But brltty doesn't start with the system.
Any advice?
Regards
Hermann
