The documentation of brltty indicates that they only use TIOCSTI as
fallback. By default a virtual keyboard device is used to simulate
typing.


Maybe it would also make sense to open a ticket to ArchLinux to enable
CONFIG_LEGACY_TIOCSTI again, as per the kernel default.

In accordance with the options help text:

"Say 'Y here only if you have confirmed that yout system's userspace
depends on this functionality to continue operating normally"

Could you create such a ticket if think it's necessary?
