$STTY  –  stty setup before command execution

$STTY defines arguments for the stty command. If this variable is defined in the environment of the command to execute, then Zsh executes stty $STTY before the command is executed.

$STTY is ignored if it’s defined in the shell’s environment and not only for the command to execute.
