/dev/console is a symlink to /dev/tty0.

Alt-F1 = /dev/tty0
Alt-F2 = /dev/tty1
Alt-F3 = /dev/tty2

... etc.

    struct termios term;

    tcgetattr(0, &term);	// Get old terminal characteristics
    (void)close(0);		// Close old terminal(s)
    (void)close(1);
    (void)close(2);
    fd = open("/dev/console", O_RDWR);
    tcsetattr(fd, &term);	// Restore characteristics
    dup2(fd, 0);
    dup2(fd, 1);
    dup2(fd, 2);

Cheers,
