My Slackware TTY can be broken easily by running:
cat some_binary_file
After the command, the entire TTY will no longer display readable characters but still responds to keyboard events.
Even if I logout and login again, the TTY is still broken and does not show readable characters anymore. I must restart the machine to restore normal TTY operation.
Is there a solution without restarting entire machine?

Run
echo ^v^o
, that isecho
and thenCtrl-v
and thenCtrl-o
, Enter. You will not see theCtrl-v
. It will display asecho ^O
.Ctrl-v
sets it into verbose mode, passing through control characters, and theCtrl-o
will reset the terminal.
