EAGLETL.EXE...........Terminal Lock Program (Eagle-TLock)

UPDATE INFO: (01 January 1990)

Version 1.00 has been update to version 1.05. Several major changes
have been coded into this version. All user keys have been changed,
they are as follows:

(Version 0.95 and below) * (Versions 1.05 and above)
Enter Password........[Any key pressed].............[F1 key]
Message Center........[Tab key].....................[F2 key]
Change Password.......[Escape key]..................[F3 key]

Also, the opening screen now goes straight to the EagleWare TLock logo
where as previous versions showed the "Enter Password" window. If any
key is pressed except the defined users keys (F1/F2/F3) nothing happens
except the logo moves around the screen. The delay for the random
printing of the logo has been changed from machine dependent clock
speed to 10 second intervals.

UPDATE INFO: (01 November 1989)

Version 0.95 has been updated to version 1.00. A message center module
has been added. Activated by the tab key (F2 key v1.05), the user can
now leave a message on his screen in two lines of text that will appear
when he leaves his system. Color changes in this message prevent screen
burn-in. To escape, press the space bar. There will be a slight delay
before returning to password.

UPDATE INFO: (16 July 1989)

Version 0.92 has been updated to version 0.95. The only major change is
the capture of the Ctrl-Alt-Del keys to prevent a system reboot. We are
currently working on also capturing the Ctrl-Alt-Esc keys used on many
AT clones to access the CMOS and the Ctrl-Alt-Ins keys used to access
the CMOS on Zenith Z-248 systems.

WHAT IT IS:

Eagle-TLock is a Terminal/System Locking program that enables a you to
leave your PC unattended for a short time without turning it off or
leaving it open to tampering fingers. This program is useful if you
need to leave your PC unattended for nature breaks, coffee breaks, etc.
want to have it on and relatively safe from snooping co-workers.

WHAT IT ISN'T:

Eagle-TLock is not a sure-fire security program and your use or misuse
of it is at your own risk. EagleWare Software Engineering does not make
any expressed or implied guarantees.


BEFORE SET-UP:

It is highly recommended that you make a back-up copy of EAGLETL.EXE in
the event that you forget your own password once you have configured
the program.

HOW TO SET IT UP:

When you first get Eagle-TLock (EAGLETL.EXE), the default password is:
NEW.

The program passwords are case sensitive, meaning "NEW" (typed in all
capital letters) is not the same as "new" (typed in all lowercase
letters).

Load EAGLETL.EXE from the DOS prompt (C:> EAGLETL). Once loaded, a box
will appear with the Eagle-TLock logo, the EagleWare name and "Enter
Password." Pressing (F1 key only - v1.05) any key will bring up a
smaller box that will prompt you for your password. Enter NEW in
capital letters. (If you make a mistake entering the password and try
to use the back space key, the program will beep and tell you that the
password is incorrect.)

To enter your own personal password, press the [Esc] key (F3 key
v1.05). The screen will clear and a box will be displayed and prompt
you for the current password (NEW for first runs). Type in NEW (or your
current password if you have previously changed it).

Once you have typed in your new password, press [Enter] and a
verification box will appear and prompt you for the same password again
to make sure you typed what you think you typed. If entered correctly,
the program will beep and tell you that the new password you entered
was accepted. That password will now be the one required in order to
exit EAGLETL.EXE.

MISCELLENEOUS INFORMATION:

All passwords entered are encrypted and cannot be viewed with programs
like Norton (c), QuickDOS II (c), etc.

You must not rename EAGLETL.EXE to another filename. If you do, the
process of changing the password which writes to the .EXE file will not
work, as it looks for the program name, EAGLETL.EXE.

The method used to encrypt the passwords is nothing fancy and can be
hacked or broken. This program is design to protect your system from
everyday tampering.

The program captures the Crtl-C and Ctrl-Break keys and cannot be
ABORTED. You have an unlimited number of attempts to enter a correct
password if you happen to forget it. The only way out of Eagle-TLock if
you do forget your password is do a cold reboot of your PC and start
over from the beginning to reconfigure it again.

After two minutes of no keyboard activity, Eagle-TLock will clear the
screen and randomly print [EagleWare * Terminal Locked] at various
locations on your monitor to prevent screen burn-in. (This Feature is
NULL with v1.05).


TEST INFORMATION:

Eagle-TLock has been tested with:

DOS versions 3.0 - 3.3
XT and AT clones
Zenith Z-248's and Z-386's
Dell 386's
Mono/CGA/EGA/VGA monitors
