Most Frequently Asked Questions
February 24, 1992
1. Q: I selected color during installation of LapLink Pro but
the program comes up in black and white. What am I doing wrong?
A: Selecting color during installation affects only the install
program. Within the main program, LapLink Pro provides several
color combination options. To select a color combination run
LapLink Pro, pull down the Options menu or press and go
to the Control Panel. Press "C" for Colors, highlight one of the
selections and press "C" for Change. You can continue to view
different color combinations by reselecting and pressing "C".
When you have found a color combination that you want to use
press "D" for Done, twice. When you exit LapLink Pro your color
combination will be saved and used in future LapLink Pro
2. Q: Every time I run LapLink Pro my printer prints some funny
characters. What's wrong? (Or, my printer does a formfeed, or
my modem resets when I don't want it to, or other unwanted
activities occur on serial or parallel ports.)
A: First, you need LapLink Pro version 4.0a (or newer). Then,
after installing and running LapLink Pro 4.0a, go to the
Port/Modem Setup in the Options menu. Select the port which is
used by your printer (or other device) and press . Once
in the Port Settings dialog, press the letter "E" to remove the
"x" from Enable Port. Press "O" for okay and "D" for done. Quit
LapLink Pro and then restart the program. It should no longer
send data to your printer or other devices.
3. Q: My computer hangs after I type in the computer name in
LapLink Pro. What's wrong?
A: You may have two serial devices (ports and/or internal
modems) configured as the same port. This problem happens most
frequently when one of the conflicting devices is an internal
modem or a port with an external modem attached and turned on.
To resolve this problem, first verify that you are using LapLink
Pro version 4.0a (or newer). Run LapLink Pro on another computer
and go to the Port/Modem Setup dialog in the Options menu.
Disable all serial ports by highlighting each port in turn,
pressing and removing the "x" from Enable Port. To
remove the "x" press the letter "E" until the "x" no longer
appears to the left of "Enable Port." Once all of the ports are
disabled exit LapLink Pro and copy the LLPRO.CFG file to a floppy
so you can then copy that file to the computer that is having
problems. You will want to copy the LLPRO.CFG file to your
LapLink directory. Run LapLink Pro. This time LapLink Pro
should load correctly. Enable one port at a time until LapLink
Pro hangs. The port that LapLink Pro hangs on will be the port
that has the conflict. You will want to keep that port disabled.
If the steps above do not help, call Traveling Software Technical
If you are using a computer running DOS 2.11, please verify that
you have LapLink Pro version 4.0 or 4.0a. The original version
of LapLink Pro (4.00) had a problem running on computers using
4. Q: I've got my two computers connected with your cable and
I've run LapLink Pro on both computers. Now what do I do? How
do I connect?
A: Look in the right window. Listed below the Available
Connections line you should see your other computer's name. For
example, it may say "Swan 486 on COM1 (115,200)" if you connected
the serial cable to COM1. This line is your gateway to the other
computer's drives. Highlight this line and press . You
should see a list of drives. If you get a message about time
differences, you will have to press before LapLink Pro
will display the drive list. Select the drive you want to access
by highlighting it and pressing .
5. Q: LapLink III works great, but I can't get LapLink Pro to
A: LapLink Pro uses a completely different communication
technique for serial connections. If you have this problem,
please call Traveling Software Technical Support for assistance
in troubleshooting this problem.
6. Q: I can't connect my Toshiba laptop with my desktop computer
in parallel mode. Serial mode works fine. Do you know what's
A: Several Toshiba (and other manufacturer brand) laptop
computers use a kind of parallel port that responds too slowly to
be used for communication. It is analogous to turning on
fluorescent lights; unlike incandescent lights, they often take a
moment before they are fully on. When LapLink Pro "looks" for
the other computer, the "lights" are off. LapLink Pro often
doesn't "see" the other computer and therefore, may not
communicate reliably with these ports.
7. Q: I'm confused about how to move around in the menus and
sometimes I wipe out my entire modem init string when I press "O"
for okay. What's wrong?
A: Here are a couple tips for moving around the LapLink Pro
dialogs: If you find that the arrow keys don't get you to where
you want to go, use the Tab key. Use the Tab key to get to the
general area and use the arrow keys to get to a specific setting
or option. Whenever the initialization string (or any other
field that can be edited) is in reverse video that means it is
selected and will be replaced by any letter you press. Press
or press the Tab key once to move out of the init string
field. Then, when you press "O" for okay LapLink Pro will accept
the modem settings.
8. Q: How do I set up a simple copy? All I want to do is copy a
couple of files (or directories).
A: Once the computers are connected and running LapLink Pro,
select the remote computer listed in the right window and then
the drive you want to access. You can copy files in either
direction from either computer. Make certain both windows are
listing files at the same level. For example, if you want to
copy a directory from the root of one computer's C: drive to the
root of another computer's C: drive, highlight the "C:\" line and
press . Repeat that step for the other window. Highlight
the directory that you want to copy in the window that you want
to copy FROM. Remember, the left window shows the files and
directories of the computer you are using. The right window
shows files and directories for the remote or other computer. If
you want to copy the directory from the other computer to the
computer you are using, place the highlight bar over the file or
directory in the right window and press the function key .
9. Q: How do I copy everything from a drive on one computer to
A: To copy everything from one drive to another you will want to
make certain that each window is displaying the files and
directories at the root level. To display the root level
listing, highlight the line that states, for example,
/"__ ____| Free: xxxk |___" and press . Once you
have done this in each window, move the focus (highlight) to the
window that contains all the information you want copied. Press
to select all files and directories. The greater-than
symbol (>) should appear next to each listing. Using the up- and
down-arrow keys move through the list until you highlight the DOS
directory. Press the Space bar to remove the ">" symbol. Next,
highlight COMMAND.COM and press the Space bar. Continue this
process until you have de-selected everything you do not want to
copy. If you are ready to start the copy process, press the
function key . By default LapLink Pro will copy across all
selected files and directories and any lower level directories.
If you have changed the Copy Options, please verify that you are
including lower level subdirectories.
LapLink Pro's clone feature also allows you to copy everything
from one computer to another. Please refer to the LapLink Pro
User's Guide for information on how to use this feature.
10. Q: How do I copy hidden system files from the root of one
computer to the root of my other computer?
A: LapLink Pro will not display or copy files in the root
directory that are marked with the hidden and system attributes.
This generally includes the special system files for DOS and
files used by other applications that are often specific to the
particular drive. If you are certain that you want to copy those
files, you will need to use the DOS utility ATTRIB to remove
either the hidden or the system attribute. Please note, DOS 5.0
and DR DOS 6.0 are currently the only operating systems that
allow you to change the system attribute. However, third party
disk utilities programs often provide a way of changing
attributes. Once the hidden or system attribute is removed
LapLink Pro will display and allow you to copy the files.
Remember to reset the attributes once the files are transferred.
11. Q: Why do I get the error "The highlighted item is not a
valid selection and cannot be copied" when I try to copy a
A: You may be highlighting a directory that is open, that is,
the directory's contents are displayed. If you are highlighting
a line that appears similar to
"__< LLPRO >______," then you are trying to copy an open
directory. To copy this directory move the highlight up one line
and press . You will then see a line that looks similar
to "LLPRO 07/11/91 06:21p." You can now press
to copy the directory, including all its files.
12. Q: Why doesn't my mouse work in LapLink Pro? It works in
A: You may be using a mouse that connects to a serial port which
LapLink Pro is trying to use. If you are using a serial mouse,
go to the Port/Modem Setup in the Options menu. Select the
serial port the mouse uses and disable that port by pressing the
letter "E" to remove the "x" before "Enable Port." Then press
"O" for okay and "D" for done to get back to the main screen.
Exit LapLink Pro by pressing and then restart your
computer. The next time you run LapLink Pro the mouse should
If you are using a bus mouse, please contact Traveling Software
Technical Support for assistance in tracking down the problem.
13. Q: Why doesn't my mouse work in LapLink Pro? It works in
A: You may not be loading a driver for your mouse. Windows
automatically loads its own mouse driver, which is used by
Windows applications. In order to work with LapLink Pro, you
will need to load a mouse driver before running Windows.
14. Q: Where is the LapLink Device Driver? I can't find it
A: Look in your LapLink III box. It should still be there. The
LapLink III Device Driver is not included in LapLink Pro. Our
user surveys indicated that only a small percentage of people
used the Device Driver, so we concentrated our efforts on making
LapLink Pro a superior file transfer product. You can continue
to use your copy of Device Driver for as long as you want.
15. Q: LapLink Pro locks up when ever I access my network
A: Many network cards use IRQ 3. That interrupt request is also
used by COM2 and COM4. To get access to the network drives you
will need to use LapLink Pro version 4.0a. Disable the serial
ports that use the same IRQ (COMs 2 & 4). You will not be able
to use these ports for communication while using LapLink Pro.
16. Q: Why do my LapLink Pro files show up in the left window
when I start?
A: LapLink Pro will always display the files of the directory
that you start the program from. For example, if you start
LapLink Pro from the root directory of your C: drive, then the
left window will display the files and directories of the root
directory. To start LapLink Pro from any directory you will need
to make certain that the LapLink Pro directory is in your path.
If you are uncertain how to make this kind of change, consult
your DOS manual or call Traveling Software Technical Support.
17. Q: LapLink Pro works great! However, every time I quit the
program my machine hangs. What's wrong?
A: You may be running a version of Direct Access that is
incompatible with LapLink Pro. Direct Access version 4.0 and
LapLink Pro are not compatible. You need to use version 4.1 or
newer of Direct Access. If you are not running Direct Access,
but are running another menu program, try using LapLink Pro
without your menu program.
18. Q: I bought the Xircom Multi-thing-a-ma-jig but I can't get
it to work. Can you help?
A: The Xircom Multiplexor allows you to use your parallel port
for both your printer and LapLink Pro. However, you will want to
follow the directions included in the LapLink Pro README.TXT
file. You do not want to run the software provided with your
Multiplexor. Plug the Xircom unit into your parallel port. Plug
the LapLink Pro cable into the "A" port of the Multiplexor. Plug
your printer into the "B" port. Run LapLink Pro and set the
parallel port to communicate in Standard (4-bit) mode, through
the Port/Modem Setup in the Options menu.
19. Q: Does LapLink Pro work with DOS 5.0 or Windows or DR DOS
6.0 or OS/2 or DesQview?
A: Yes, yes, yes, yes and yes. LapLink Pro is compatible with
DOS 5.0 and DR DOS 6.0. LapLink Pro will work in Windows and
DesQview. Please refer to the Windows section of chapter 10 in
the LapLink Pro User's Guide for more information on the special
considerations when working within the Windows environment. In
DesQview you will need to give LapLink Pro control of the
appropriate port. Go to "Change a Program" in the main DesQview
menu. Place a "Y" in the option asking whether the program uses
the serial ports.
To use LapLink Pro in serial mode in the DOS compatibility box in
OS/2 (version 1.3 and earlier) you will need to type the
No special commands are necessary for connecting in parallel
20. Q: Can I use a longer cable?
A: The simplest way to extend either the serial or parallel
cables is to purchase a "straight-through" cable with a male
connection on one end and a female connection on the other end
and connect this to one end of the LapLink Pro cable. A
"straight-through" cable connects the pins at each end, matching
pin functions. It is a very common cable and should be available
at computer stores. We recommend a total cable length of no more
than 100 feet (30 meters) for serial connections and 20 feet (7
meters) for parallel connections.
21. Q: How do I get LapLink Pro to work in 8-bit mode? It
always switches to standard 4-bit when I copy.
A: LapLink Pro automatically detects whether the two computers'
parallel ports support 8-bit mode. You cannot force LapLink Pro
to use 8-bit parallel mode.
22. Q: How do I change to a different drive?
A: To change to a different drive you can press the key
to move the focus to the very beginning of the list. Use the
down-arrow key to highlight the line that has the computer name
and press . You should see a listing of the available
drives. Select the drive you want by highlighting it and
pressing . You can also change drives by using the Change
Directory command in the Disk menu. Press to access the
Disk menu, then select Change Directory. Type in the drive
letter you wish to change to and press .
23. Q: My modem is not listed in your modem settings dialog.
How do I use an unsupported modem?
A: Even though LapLink Pro does not specifically support your
modem there are several things you can try to get it working.
-Try the Hayes Compatible init string.
-If you use a 1200 baud modem, try using Q0X1 as your
init string and verify that the baud rate is set to
-If your modem supports V.42bis data compression and
error correction, try Q0X3&C1&D2 as your init
-If your modem supports MNP5 data compression and error
correction, try X3&C1&D2\J1\N3\Q3\V1\G0 as your init
-If you are uncertain what kind of modem you use, call
Q: Why do I always get the message "Modem initialization
failed" when I try to dial out?
A: Several things can cause this error message. If you have
already checked that the init string is correct for your modem
and verified that the modem is on and connected correctly, then
you may have what is called an interrupt conflict. An interrupt
conflict arises when two devices use the same IRQ setting. This
often occurs when you have more than two serial devices,
including internal modems. COM1 and COM3 often share the same
IRQ number and COM2 and COM4 often share the same IRQ number.
Therefore, when you are using a modem you will want to disable
the port's partner. For example, if you use a modem on COM3,
disable COM1. You can disable the ports by going to the
Port/Modem Setup dialog in the Options menu. Select the correct
port and press . Press the letter "E" to remove the "x"
from Enable Port and then "O" for okay.
