- PROGRAM OPERATION
- -----------------
-
- Hello, and welcome to the PW password program. As you have
- probably noticed by now, this program is extremely easy to use and needs
- very little explanation. I'll just give a quick rundown on how to start
- and setup the program.
-
- First, there isn't a default password. You'll have to go to the
- Setup Menu to set a password. So now, lets get the program up and
- running by typing: PW <Enter>. If the program has never run before, a
- Menu will pop up telling you that the Password is Not Installed along
- with two selections to choose from. If you would like to return to DOS
- you can press the down arrow to move the bar to the Return to DOS
- selection and then press the Enter key, or just press the Escape key to
- return to DOS. But for now, we would like to Setup a password and a few
- options so we'll just press the Enter key and go to the Setup Menu.
-
- Here you'll have six options: Setting a password, Setting
- Options, User identification, View the disk logfile, Exiting the Setup
- Menu, and Returning to DOS. NOTE: You cannot exit the Setup Menu unless
- a password has been set. If you try, you will receive an Error message.
- Ok, lets set a password. With the selection bar on Enter a password,
- press the Enter key. A small window will pop up prompting you to enter
- a new password. If you would like to not enter a password at anytime,
- just leave the line blank and press the Enter key. Note: If you make an
- error while entering your password choice, press the Escape key and the
- entry will be cleared (the backspace key also works). Now type in a
- password of your choice and carefully check it over to make sure it's
- right. When your satisfied, press the Enter key to save the password.
- You will be returned to the Setup Menu.
-
- Now let's set some options. Press the down arrow to move the
- bar to the Set Options selection and press the Enter key. The Options
- Menu will pop up. Anytime that you would like to Quit the Options Menu
- without saving anything, press the Escape key and you will be returned
- to the Setup Menu. Now, let's say that you want to set the options of
- Logging Unauthorized attempts to a disk log file, having the screen
- clock & Log time stamp appear in 24 hour format, enabling the audible
- alarm, and also have some personal user identification appear on the
- screen just incase your computer is ever stolen or misplaced. You would
- just press any of the (up, down, page up, page down, home, end) keys to
- move the selection bar to your choice and then press the Space Bar to
- toggle the selections. A small check mark will appear next to your
- selections. When you are done, press the Enter key to Save your choices,
- or press the Escape key to cancel.
-
- Ok, were now back at the Setup Menu. Lets now choose the User
- Identification selection. Here all you have to do is enter some
- personal info as you see fit. You can move between the selections with
- the same arrow keys as before. When done, press Enter to Save or ESC to
- cancel. You will automatically pop back to the Setup Menu.
-
- The next selection on the setup menu is the logfile viewer.
- Here you can effortlessly browse through the logfile that been recorded
- to disk by using the (up, down, page up, page down, home, end) keys.
- Also, when you feel that the logfile is getting to large to manage, you
- can always press the Delete key which will then prompt whether or not to
- delete the logfile. Pressing (y or Y) will delete the logfile. Escape,
- (n or N), or Enter will cancel. Also, it does not matter what
- attributes have been set to the logfile, it will be deleted.
-
- Let's now Exit the Setup Menu and get to the main screen (the
- screen which you will now see first whenever you run PW). Here you'll
- see a brief warning message meant to deter Unauthorized users, and you
- have two selections: Enter Password or Setup Menu. If you would like to
- return to the Setup Menu, move the selection bar and press the Enter
- key. You will notice that you now have to enter your password in order
- to return to the Setup Menu. Type in your password (Dots will echo to
- prevent onlookers from seeing your password) and press Enter. If you
- entered your password in correctly you will be returned to the Setup
- Menu, and if not, returned to the main screen. Ok, let's return to the
- main screen and press the Enter key to enter our password. Note that we
- will have only two attempts at entering the correct password, or else
- the system will be disabled and the alarm will sound. Go ahead and enter
- your password and press the Enter key to return to the DOS prompt.
-
- And there you have it. All that's left to do is start up your
- favorite text editor and place the letters PW as close to the top of
- your AUTOEXEC.BAT file as possible.
