KEYLOCK HELP.... Some information on using KEYLOCK
            --------------------------------------------------

   KEYLOCK is a memory resident utility which enables the keyboard  to 
be  locked at any time with a simple key sequence. The  keyboard  will 
remain  disabled until a predefined password of up to 8 characters  is 
entered.

KEYLOCK is invoked from the DOS prompt as follows
=================================================

           A>KEYLOCK {function key number}


           where

               {function key number}

                       a  function  key  number  in  the 
               range 1 to 10.

       The  function  key  number determines the  key  sequence  which 
activates the lock.

       On  entering the KEYLOCK command the utility will prompt for  a 
password.  At this point, up to eight characters may be entered  which 
are  not echoed on the screen. On entering the password,  the  utility 
will  prompt for verification and the same character sequence must  be 
re-entered.  If the verification fails then the password must  be  re-
entered  until  verified correctly. The resident part of  the  utility 
will then be installed.






















KEYLOCK may also be invoked from a batch file as follows
========================================================

           A>KEYLOCK {function key number} {password} > NUL


           where

               {function key number}

                       a  function  key  number  in  the 
               range 1 to 10.

               {password}

                       a password up to 8 characters  in 
               length.


               > NUL

       The  function  key  number determines the  key  sequence  which 
activates the lock as before.

       To  facilitate  the  use  of the utility in  a  batch  file,  a 
password  may  be  entered  as  the  second  parameter.  The  password 
specified  in this way will not be verified, the installation must  be 
tested at least once at a non-critical point.

       As  the  password  will be displayed when  the  batch  file  is 
executed,  it is best to place an ECHO OFF command in the  batch  file 
before the KEYLOCK command.

Locking the keyboard
====================

       The  lock  is activated by holding down both the Ctrl  and  Alt 
keys  and  pressing  the  function  key  as  specified  in  the  first 
parameter.  A long beep will be heard indicating that the keyboard  is 
locked.

       When  locked,  non of the keyboard functions will  operate  and 
nothing will be entered in the keyboard buffer.

       The lock may be activated at any time whatever the computer  is 
doing.







Unlocking the keyboard
======================

       The  keyboard  can only be unlocked by  entering  the  password 
specified  during  installation. A short beep will be heard  for  each 
correct character typed. Once the correct character sequence has  been 
entered,  a  long beep will be heard indicating that the  keyboard  is 
unlocked.
