An interesting question about "print '\a'"

[Anthony Liu]

We know that if we do

print '\a'

the bell will sound.

Now, why do I hear the sound on my local machine when
I run a python script on a remote host?

I understand if I hear it when I do

print '\a'

on my local machine.

Does the command get sent back to the client machine?

Thanks.

Because print '\a' just prints the BEL ASCII character, which most
terminals respond by beeping. Since, when you're logged into a remote
machine, it's your terminal that's displaying the output of your remote
session, that's why you hear the beep on your local machine.

The code is printed to stdout, which is your terminal. Your
terminal interprets ^G as a beep.

I thought that is just a "terminal" thing(extend ASCII that interpreted
by the terminal)? If you have a terminal attached to a host, shouldn't
this be making sound on the terminal rather than the server ? This not
alsa or output to the server device, but straightly sending '\a' back
to the client machine I believe.
