I apologize for putting together a rather vague note. I am running X11R2
on a sun 2/170 and SunOS 3.5. I start x via the alias

	alias x 'xinit uwm -- Xsun'

To use X while in sunview I simply type `x' in an of the sunview windows.
Once I exit X, I get back into sunview and all the windows I had. One of
these windows is the console window (via the -C option in .suntools).

I did get two reponses back. mlandau@diamond.bbn.com sent me the following
C program preceded by instructions. I compiled it and saved it in `xtop'

	% cc -o xtop xtop.c

My default .suntools file opens a few windows one of which is designated
as the console, i.e.,

 cmdtool -Wp 652 73 -Ws 495 434 -WP 0 0 -Wl "<< CONSOLE >>" -WL console -C

I determined what ttyp? was the console via `ps'

 7025 p1 I  3:25 cmdtool -Wp 652 73 -Ws 495 434 -WP 0 0 -Wl << CONSOLE >> -W

and issued the command 

 % xtop /dev/ttyp1

I then started x, did a y amount of work and exited. When I got back to
sunview, I checked whether the console was still bound the cmdtool window
defined to be the console,

  % cat >/dev/console
  Hello world!
  ^D

the message appeared in the window. Others using X on top of sunview may
wish to give this program a try. Matt Landau mentions that he instructs
his users to run the program after running X.

In comp.windows.x (<26900028@uiucdcsm>), you write:

This is a well-known problem.  What I do is have users run the following
little program after running X on top of SunView.  Given a tty name, it
makes that tty the console.  With no argument, it makes the current window
the console.


#include <stdio.h>
#include <errno.h>
#include <sys/file.h>
#include <sys/ioctl.h>

extern char *rindex ();
static char *ProgName;

main (ac, av)
int	ac;
char	*av[];
{   
    int		fd;
    int		on = 1;
    char	*p, *name = NULL;
    char	prelude[80];
    
    if ((p = rindex (av[0], '/')) != NULL)
	ProgName = p+1;
    else
	ProgName = av[0];
    
    switch (ac)
    {   
      case 1:
	fd = fileno (stderr);
	break;
	
      case 2:
	name = av[1];
	fd = open (name, O_RDWR, 0777);
	break;
	
      default:
	fprintf (stderr, "usage: %s [ttyname]\n", ProgName);
	exit (1);
    }
    if (fd < 0)
    {   
	sprintf (prelude, "%s: %s", ProgName, name ? name : "stderr");
	perror (prelude);
	exit (2);
    }
    if (!isatty (fd))
    {   
	fprintf (stderr, "%s: %s is not a tty device\n", 
		 			ProgName, name ? name : "stderr");
	exit (3);
    }
    if (ioctl (fd, TIOCCONS, &on) < 0)
    {   
	sprintf (prelude, "%s: cannot make %s the console", 
		 			ProgName, name ? name : "tty");
	perror (prelude);
	exit (4);
    }
    if (name) close (fd);
    return (0);
}

Do  not use an xterm as the console in this case.  Omit the -C flag.

There is no way to save and restore console-hood.
