Thanks to all of you who responded to my above question. First of all, I
have to apologize for the mistake that the Solaris version should be 2.3
instead of 1.3

Here is a summary of the resopnses:

anthony.baxter@aaii.oz.au
-------------------------
Run xdm, or copy the screenblank command from a Sunos4 machine.

worsham@aer.com
---------------
  "screenblank" is not "yet" provided with Solaris, but you can copy
  it over from one of your SunOS machines and add a script to /etc/init.d
  to start it (it will run under binary compatiblity). The script we use
  is below (/etc/init.d/screenblank):

#ident "@(#)ANNOUNCE 1.6 92/07/14 SMI" /* SVr4.0 1.1 */

echo 'starting screenblank.'
/opt/bin/screenblank

  Note: you will have to have a link from /etc/rc3.d to this file,
        i.e. /etc/rc3.d/S50scnblk --> /etc/init.d/screenblank

No, there is no such command on solaris OS, but I get the source code.
The following two emails contain C source code and manpage.

teh@chinook.phy.anl.gov
-----------------------
How about the generic xlock program that comes with the X11 windows system?
It is not quite a screenblank but it blank the screen and in addition lock
the console from being used by someone else.

gm@informatik.tu-cottbus.de
---------------------------
Use the SunOS 4.1.3 scrennblank. It works fine under Solaris 2.x.

tmk@mayo.edu
------------
Attached is a tar file containing screenblank. It has been working fine for
me under Solaris-2.3. I got it over the network a while back. Hope it helps.

symanski@gold.nosc.mil

Many people will probably suggest xautolock.

You can probably find it with gopher or archie.

Here is what I got:

                    Search of archive sites on the internet: xautolock

 --> 1. ftp.wustl.edu:/usenet/comp.sources.x/volume17/xautolock//
      2. harpo.seas.ucla.edu:/mnt/fs01/xautolock//
      3. harpo.seas.ucla.edu:/pub/xautolock.

gmerin@panix.com
----------------
check out the manpage on xset with the -s parameter:

     s The s option lets you set the screen saver parame-
             ters. This option accepts up to two numerical
             parameters, a 'blank/noblank' flag, an
             'expose/noexpose' flag, an 'on/off' flag, or the
             'default' flag. If no parameters or the 'default'
             flag is used, the system will be set to its default
             screen saver characteristics. The 'on/off' flags
             simply turn the screen saver functions on or off.
             The 'blank' flag sets the preference to blank the
             video (if the hardware can do so) rather than
             display a background pattern, while 'noblank' sets
             the preference to display a pattern rather than
             blank the video. The 'expose' flag sets the prefer-
             ence to allow window exposures (the server can
             freely discard window contents), while 'noexpose'
             sets the preference to disable screen saver unless
             the server can regenerate the screens without caus-
             ing exposure events. The length and period
             parameters for the screen saver function determines
             how long the server must be inactive for screen sav-
             ing to activate, and the period to change the back-
             ground pattern to avoid burn in. The arguments are
             specified in seconds. If only one numerical parame-
             ter is given, it will be used for the length.

I run a SunOS 4.1.3 /bin/screenblank on my Solaris 2.3 SLC in BCP mode
Works ok!

curnutt@Stoner.COM
------------------
Solaris FAQ:
72) Where is the Solaris2.x screenblank?

      You can either run the 4.1.x screenblank in compatabilty
      mode or you can compile you own from sources available
      on thor.ece.uc.edu. Get the file /pub/sun-faq/screenblank_21dec93.tar.Z.

pablo@muaddib.itas.uh.edu
-------------------------
        With the openwindows running, look at the workspace properties. Each
user can set the screensaver option under category miscellaneous.

I prefer the solution suggested by worsham@aer.com, BTW, I really should check
up the Solaris FAQ first before posting this simple question. Sorry again, and
thanks for your patience and still many quick responses. Thanks a lot.
