Yes, I think there would at least need to be an operation to query 
BRLTTY for information about the keys and controls of the active 
display, or, failing that, the manufacturer/model of device being used.

Every other screen reader I've used has access to the underlying device 
controls, with default command bindings for each supported display type.

As many displays have braille input keys, a common command set can be 
assigned to them, eliminating a lot of device-specific configuration.
