Your abstract questions of late need the context of a commercial requirement.

Hard to guess the requirement in this case:

1) If you are trying to write shell to answer the SSH question, it is better to configure the system so it does not ask the question.

2) If you just need to record screen output for documentation purposes, maybe consider quality PC-based terminal emulation software with screen logging features. This is not quite as sophisticated as it sounds because CRT terminals in the 1980s were capable of repeating the screen output to a serial port on the same terminal.



Ps. We don't want to make public information about unix terminal I/O which would assist anybody to write a keylogger, a password cracker or a virus.

flash

curs_beep(3CURSES)					     Curses Library Functions						curs_beep(3CURSES)

NAME

       curs_beep, beep, flash - curses bell and screen flash routines

SYNOPSIS

       cc [ flag ... ] file ... -lcurses [ library ... ]
       #include <curses.h>

       int beep(void);

       int flash(void);

DESCRIPTION

       The  beep() and flash() routines are used to signal the terminal user. The routine beep() sounds the audible alarm on the terminal, if pos-
       sible; if that is not possible, it flashes the screen (visible bell), if that is possible. The routine flash() flashes the screen,  and	if
       that  is not possible, sounds the audible signal. If neither signal is possible, nothing happens. Nearly all terminals have an audible sig-
       nal (bell or beep), but only some can flash the screen.

RETURN VALUES

       These routines always return OK.
