<STRONG>echo</STRONG> and <STRONG>noecho</STRONG> determine whether characters typed by the user are
written to the <EM>curses</EM> window by the input character reading function as
they are typed. <EM>curses</EM> always disables the terminal driver's own
- echoing. By default, a <EM>curses</EM> window has its echo flag set. Authors
- of most interactive programs prefer to do their own echoing in a
+ echoing. By default, a <EM>curses</EM> screen's echo option is set. Authors of
+ most interactive programs prefer to do their own echoing in a
controlled area of the screen, or not to echo at all, so they call
<STRONG>noecho</STRONG>. The man page for the input character reading function
discusses how <STRONG>echo</STRONG> and <STRONG>noecho</STRONG> interact with <STRONG>cbreak</STRONG> and <STRONG>nocbreak</STRONG>.

Initially, whether the terminal reports a carriage return using the
- character code for a line feed depends on the configuration of the
- terminal driver; see <STRONG>termios(3)</STRONG>. <STRONG>nl</STRONG> configures the terminal to perform
- this translation. <STRONG>nonl</STRONG> disables it.

+ (or "cooked") mode, the terminal driver always translates carriage

In each case, the function returns
- <STRONG>1</STRONG> if the flag is set,
