Echoing control characters on the crt (System V)

[John L. Wynstra]

	I had an experience the other day.  I was "doctoring" a program I
had running on one machine [the Altos 2086, runs XENIX 3.4] to run on the
Altos 1000 [in effect a System V on a 386].  The program emits a Ctrl-G
in response to an error (via "curses" in raw mode, no echo).  On the 2086
a bell sounds.  On the Altos 1000 it displays ^G on the screen.

	I immediately thought of Berkeley's ctlecho feature on the stty,
and checked our manual, but discovered no such analog on the System V.

	Just to further define this problem, I tried an experiment, I did
a stty -echo and keyed in a Ctrl-G, the Altos 2086 replies "<bell sound>: not
found", but on the Altos 1000 it replies "^G: not found".  What is going on
here?  Is there a way I can tell the System V tty driver to not echo control
characters, a la Bsd's "stty -ctlecho"?
