Thanks for the pointer.
And regarding the trigger - I've tried below use case
on my desktop Debian:
Ctrl+Alt+F3 to change the console
Then logged in and executed tty command:
$ tty
$ /dev/tty3
$ cd /sys/class/leds/input5\:\:capslock
note: this is LED on my USB keyboard and it works correct
with e.g. timer trigger
/sys/class/leds/input5::capslock$ echo tty > trigger
$ cat /sys/class/tty/tty3/dev > dev
Type some characters.
LED does not blink.
$ echo "aaa" > /dev/tty3
$ aaa
LED also does not blink.
I assume this is correct test case for tty trigger?
