Public bug reported:

The command line utility "stty" from the package "coreutils" forgets to
turn on local echo in cooked mode. That mode doesn't make much sense for
most of *NIX land without the local echo and especially the Bourne Again
SHell is not able to reset a terminal device to a sane configuration to
ensure regular operation.

Instead of providing good defaults for the cooked mode "stty" introduces
an otherwise unknown "sane mode" which is hard to track in the sources
and probably shouldn't even exist. I don't want to call it crippled but
a lot of software "under the wings" of the FSF ...

As a reminder: modern terminals are virtual and have a lot of flags to
change behavior. But there are two main modes: one teletypewriter mode
with integrated line editing and buffered input/output suited for
command line shells based on cooked or canonical mode and then a raw
mode where an application like VIM or Lynx takes control of the
terminal. A new sane mode shouldn't really be necessary if not for other
devices like modems/serial lines but the documentation doesn't know
anything about this.

End Of Message

Trivia: The control key can be seen as a bitmask applied to regular
upper case characters and this can even match the input routines. End of
File can be mapped to up to two other keys - that is customization!
