[BRLTTY] Skip identical blank lines setting seems to impact Orca

[Chevelle]

Hello, I'm still using 6.8.
I made a python script that prints out the key presses returned by BrlAPI.
When 'skip identical blank lines' is set to yes:

LNUP becomes PRDIFLN
LNDN becomes NXDIFLN
I don't think Orca knows about this, so the up and down buttons don't 
work.  What is the best way to handle this.  Can Orca query the setting 
of 'skip identical blank lines', or map both sets of keys, or should 
something be changed in Brltty?  I'm not sure if other Brltty settings 
can impact Orca?

Thanks for any insight.
