This module generates soft clicks as printable characters are sent to the
foreground tty.
These sounds simulate an old fashion teletype running at 2400 baud.
This serves as valuable feedback for a blind user,
even if speech or braille is not working.
And there are many reasons
d you can edit the file as usual, or quit.

I guess the tty is an incredibly complicated beast.

to the next release, and perhaps backport
if possible; for those of us in cooked line mode
it was really an inconvenient bug.
Finally, my complements to you.
I read the code in n_tty.c and I don't understand any of it.
It's way beyond me.
Nice job, and thank you.

The speaker driver can play a tone at a specified frequency,
or the standard control G bell,
which is a special case of TONE at 1000 hz 0.1 seconds.
This patch adds kd_mkpulse() to generate a soft click.
This is introduced to support accessibility modules and adapters in the
ping to fix this problem,
but it remains.

problem.
Thank you for your quick reply,and the patch to try.
I'm afraid however this is still an unsolved problem.
Realize that it pops up rarely and randomly in just about any cooked program;
I chose the console switch example because it most reliably reproduces the bug.
Thank you.

I looked through MAINTAINERS but couldn't find
a clear maintainer for drivers/tty/tty*.c
Please forward this to the appropriate people.
Thank you.

long with this,
I can write a patch for drivers/Makefile and drivers/Kconfig
that would put this in place.

Your thoughts are welcome.

I think there is general agreement, including myself,
that led state should be part of the key event, like shiftstate,
and not grabbed asynchronously after the fact.
So here is the patch that would do this.
I tested it with my keyboard modules and it works.
It only changes a couple lines of code, a
ead and write files under /proc.
I'm sorry, but I think it's cool.
Cool or not, it seems to be here to stay,
and I humbly suggest a standard location for adapters and their virtual files.
