- ADDENDUM TO PADLOCK.DOC FOR PC PADLOCK V2.3
- -------------------------------------------
-
- Several new features have been added to PC Padlock V2.3 that were unable to be
- included in the printed manual. They are the monochrome mode, activity
- logging, drive/disk changing, and corruption protection. Please read this
- document in it's entirety, especially if you desire logging or are a network
- user. Here is how to operate these new functions :
-
- MONOCHROME MODE
-
- A new command line switch, "/m", will cause PC Padlock to come up in black and
- white (monochrome) mode. This is useful for mono monitors, as well as laptop
- and notebook computers. To use this feature, simply type "padlock a: /m" from
- the DOS command line, or see the section on ALTERNATIVES TO COMMAND LINE
- SWITCHES later in this document.
-
- ACTIVITY LOGGING
-
- Another command line switch causes PC Padlock to log all successful locking,
- unlocking, clearing, encryption, decryption, and purging to a text file. This
- file will contain one line for each entry, with the date and time it occurred.
- To log all activity for a session, type "padlock a: /l" from the DOS command
- line, or see the ALTERNATIVES TO COMMAND LINE SWITCHES section. Unless the
- environment variable mentioned in this section is used, this file will be
- named "pcpl0000.log" by default. It may be viewed, edited, deleted, or
- printed.
-
- DRIVE/DISK CHANGING
-
- You no longer have to enter the drive letter from the command line when using
- PC Padlock. Merely type "padlock", and when the program comes up, it will
- prompt you to select a drive letter. You may do this either by hitting the A
- or B keyboard keys, or clicking the mouse over the A: or B: blocks located in
- the DISK INFORMATION header. Also, you may change disks in a drive while the
- program is running, or select a new drive letter altogether. Just select the
- new disk or drive as before, once the desired disk is in the drive.
-
- NOTE
-
- Do not remove a disk while PC Padlock is performing any of it's functions such
- as locking or encrypting. Your disk may be permanently damaged.
-
-
- ALTERNATIVES TO COMMAND LINE SWITCHES
-
- The command line can get somewhat long, especially if you are using both
- switches, such as "padlock a: /l /m". There are several methods to cutting
- down the typing time on lines such as these. One is to use the environment
- variable built into PC Padlock. This variable is "pcpl", and the first
- character denotes color or monochrome mode. This is followed by a comma and a
- four character designation for the log file. The log file designation must be
- four characters long. Here are some examples, assuming you use no command
- line switches :
-
- no environment variable color mode, with no logging
- set pcpl=c color mode, with no logging
- set pcpl=m mono mode, with no logging
- set pcpl=c,0001 color mode, with log file named "pcpl0001.log"
- set pcpl=m,dave mono mode, with log file named "pcpldave.log"
-
- To setup the environment variable, use any text editor and edit your
- "autoexec.bat" file, located in your hard drive's root directory. Then simply
- add the appropriate line, such as "set pcpl=m", anywhere in the file. The
- next time you reboot your computer, the options you selected will be automatic
- every time you run PC Padlock.
-
- Other alternatives include using the doskey program in DOS V5.0 or later. An
- example of this would be to add the line "doskey pl=padlock $* /l /m" to your
- autoexec.bat file. You could then simply type "pl" or "pl a:" to start the
- program. Or you could write a batch file to do the job. See your DOS manual
- for more detail on these functions.
-
- IMPORTANT NOTE FOR NETWORK USERS
-
- If network users desire activity logging, each computer on the network must
- use the environment variable method and specify a different four character
- designator for the log file name. Failure to do so may result in incomplete
- logs and/or program abortion.
-
- QUALITY CHECKING
-
- Several things can damage a floppy disk that are completely beyond the control
- of the PC Padlock program itself. Although these conditions are rare, their
- detection and prevention are now built into the program.
-
- Floppy disk failure itself can cause data corruption. We all have had a
- floppy or two at one time or another that just suddenly went bad and was
- unusable. This is more likely to happen with off-brand or generic disks, and
- also disks that are used constantly for long periods of time. Although most
- manufacturers guarantee their disks for life, it is just good common computer
- sense to replace heavily-used disks on a yearly basis. Nonetheless, PC
- Padlock will now make every effort to detect bad disks and abort the program
- if the disk looks strange in any way.
-
- Disks are also scanned for any non-standard DOS formatting scheme. Numbers of
- sectors, clusters, sectors-per-cluster, and other data is checked against
- accepted norms, and the program refuses to operate on any disk it senses to be
- non-standard.
-
- A brief interruption in power to the system or a general computer "glitch"
- itself can sometimes confuse an already running program. If any of these
- situations cause a data inconsistency, the program will shut down and return
- to DOS.
-
- PC Padlock will not only check for these situations with each new disk, but
- also before every function it performs on the disk. This affords the user
- maximum protection against bad or damaged disks.
