DESCRIPTION
       The  echo() function enables Echo mode for the current screen. The noe‐

       curses  software echo mode is enabled and hardware echo mode of the tty
       driver is disabled. The echo() and noecho() functions control  software
       echo  only.  Hardware echo must remain disabled for the duration of the
       application, else the behavior is undefined.

RETURN VALUES
       Upon successful completion, these functions return OK. Otherwise,  they
       return ERR.
