i must had to say: not suitable for brltty, but brltty use ioctl... as you said.

not wrong but, only not suitable for brltty.

1. i don't realized that brltty retry the device connection if lost:

brltty -b ts -d /dev/cuaU0
	brltty start fine!

stty -f /dev/cuaU0 whatever_speed_you want, or minicom... from another user 
in multi user as normal...

	braille lost!

the only way to reestablish the connection with the braille device, i found is:
switching off the braille display and on, again.
perhaps (???) a lock on the device would help for this purpose; but,
my knowledge of brltty is at the beginning.
