Yes, the focus goes, but the point of giving an empty path is to ignore
the focus and get keyboard events anyway. Did you also use
brlapi_acceptAllKeys()?

There is one: brlapi_writeDots.

You can also just use the 256 unicode braille patterns: U+2800 ...
U+28FF. This permits to intermix raw braille and text left for brltty to
translate.

This is possible, just not easily configurable for now, you have to set
retainDots to 1 in Programs/brlapi_server.c and rebuild brltty. Yes,
there are plans to make it configurable from the brlapi client.
