[BRLTTY] Python brlapi and translation table question

[scott at bashautomation.com]

Hello. A few questions for the team.

1.  Are the translation tables able to be swapped out at runtime.  If not,
are there any plays for such a feature.

2.  I am very confused about the AND/OR properties of the Write class. 
Could you please give a small snippet showing an AND/OR operation
(preferably in Python) and the expected result.

3.  The latest update includes the displayNumber property in the Write
class.  I have not been able to connect with the latest version.  Any help
here would be greatly appreciated.

4.  On a real devices with a display of say 40x3, can it be viewed as a
display of 120 sequential characters or is it more complicated than that.

Thankyou for your help.
Scott
