The program LOCKERUP.EXE is designed for those offices like
mine where too many people have access to my PC when I'm
not sitting in front of it.
To use this program just type LOCKERUP at the DOS prompt. It is
recommended that you include this program in your AUTOEXEC.BAT
file under another name like TIMER, or something else that will
not give a tip-off that you are locking up your keyboard. As
soon as you run this DOS resident program, your keyboard will
lock up until you depress the "Alt key", the "Left-shift key"
and the letter "U" or "u" (which stands for unlock). To lock up
the keyboard, depress the "Alt key", the "Left-shift key" and the
letter "L" or "l" (which stands for lock).
This three key combination can be changed by using DEBUG in the
following manner:
(1) COPY lockerup.exe junk
(2) DEBUG junk
the bytes at location
303 equals 26 which is the scan code for the letter "L" or "l"
304 equals 16 which is the scan code for the letter "U" or "u"
305 equals 0A which is the bit map within KB_FLAG
:...................
:
RIGHT_SHIFT = 01H :
LEFT_SHIFT = 02H...:
CTL_SHIFT = 04H :
ALT_SHIFT = 08H...:
Example :
the following debug commands will change the program so that
it is necessary to use the letter "S" or "s" to lock the keyboard
and the letter "G" or "g" to unlock the keyboard in conjunction with
the "Ctrl key", and the "Alt key"
