Ok, as I have seen, it seems suitable but it has one problem. To call
the ioctl I need to pass a file descriptor, and if I'm ok, it is the
one for the tty I want to write to. So I should open /dev/ttyE0, for
example.
But I can't do this. I need to write to the active console, no matter
which one it is. For now, I only open /dev/ttyEcfg and work with
ioctl's on it, which do not depend on a concrete console.
So should I go on and create a new ioctl for this? Or is it there a
way to get this one working (TIOCSTI)?
Thank you.
