Problems with cursor routing and copy/paste in BRLTTY

[Odd Martin Baanrud <martin@lb7ye.net>]

Hello,

I’m running Debian 12, with backports enabled.
For some time, cursor routing and copy/paste in BRLTTY has not worked.
When I press a cursor routing key, or try to paste something from the BRLTTY buffer, I get the following message:
“Linux character injection (TIOSCSTI) is disabled on this system”
What does that mean?

Regards, Martin
