                       TSN COMMON PROBLEMS & SOLUTIONS
                       ===============================

This following information was developed after the TSN manual
was printed.  If you're having difficulty installing or running TSN,
please read this document carefully.

CAN'T HEAR THE MODEM DIAL -
-------------------------
If you can't hear the modem pick up the phone and dial, then TSN is
having trouble finding your modem.  You may need to change the COM
port setting for TSN.  To do this, go into the directory into which 
you installed the TSN software, run the Install program, and choose 
"COM Port" from the menu and select a different checkmarked selection.

NOT ENOUGH MEMORY -
-----------------
If you get the message "Not Enough Memory..." before starting TSN or
during game play, you need to make a DOS Boot Disk.  A Boot Disk
will create an optimal setup for your computer to install and play
TSN.

To make a TSN Boot Disk run the Install program from either the #1
diskette (if you haven't already installed the software) or from 
the directory into which you installed the TSN software.  Choose the
"Make bootable floppy disk" option from the menu.  After creating 
the Boot Disk, restart your computer with the Boot Disk still in 
the A: drive.

TSN GIVES AN ERROR #12 -
----------------------
Make sure you've chosen the modem brand that you have installed in
your computer.  You can re-run the Install program to check what 
brand modem you have installed and change it to the correct brand if
necessary.  For additional information on this problem, see the
technical information on Error #12 below.


                   ADDITIONAL TECHNICAL INFORMATION
                   ================================

MORE ABOUT COM PORTS -
--------------------
If you have an internal modem, please examine the COM port settings
of any previously installed Asynchronous Communications Adapters
(ASYNC) or multi-function boards, as well as the COM port setting of
the internal modem, to ensure there are no addressing conflicts.

COM ports 1 and 3 share IRQ #4.  COM ports 2 and 4 share IRQ #3.  
We recommend that if you have a mouse on COM 1 you should set your
internal modem to COM 2.  If another device in your computer
conflicts with COM 2, try setting your modem to COM 4.  Avoid using
COM 3 if you have a serial mouse on COM 1.

MORE ABOUT BOOT DISKS -
---------------------
A Boot Disk will allow you to bypass your computer's normal
configuration to create an optimal environment for installing and 
playing TSN.  To make a TSN Boot Disk, run the Install program from 
either Disk #1 (if you have not already installed TSN) or from the 
directory into which you already installed TSN.  Next, select "Make 
bootable floppy disk" from the menu.  After creating the Boot Disk, 
restart your computer with the Boot Disk still in the A: drive.

A Boot Disk will not alter your existing system configuration.  Your 
computer is designed to recognize a Boot Disk in the A: drive as an 
alternate method of starting and configuring itself.  You might think 
of the Boot Disk as your TSN Startup Disk.  It's the best method we 
have of ensuring that your memory configuration is set to best run 
TSN.

SOUNDBLASTER - ADLIB -
--------------------
Since TSN uses mostly FM synthesis music, you can eliminate many
Sound Blaster conflicts by simply choosing AdLib as your music 
device in the Install program.

OF MICE & MODEMS -
----------------
If you have an internal modem and a serial mouse you must make sure
that they aren't both using the same COM port.  Your modem and 
mouse each need their own COM ports and IRQ interrupts.  Setting 
both mouse and modem to the same COM port or interrupt may cause
problems.  Changing your modem to COM 2 or COM 4 (see your modem
instruction manual for directions) should resolve most conflicts.

AN ENEMY PLANE SHOT DOWN MY MOUSE -
---------------------------------
Occasionally, on a few brands of computers, you might find that your
mouse is misbehaving after a game of Red Baron.  Perhaps every time
you click on something, you get help instead of actually doing what
you told your computer to do.  What's happening is that your
computer thinks you are pressing one of the shift keys.  You can fix
the problem by pressing and releasing the two shift keys (you don't
have to press them at the same time.  Just press and release each
one).

I CAN'T GET THERE FROM HERE (reconnect failure) -
-----------------------------------------------
When you move from one area to another on TSN you actually change
from one host machine to another.  Although you can't see it, your
software tells the network to disconnect you from your current host
machine and connect you to another one.  In order for the network 
to get the message to move you, it must receive a break signal from
your modem.

If your modem isn't configured properly, the break signal may not be
passed through to the network properly.  If this occurs you will see
a "Reconnect failure" error message and TSN will automatically
redial the modem to re-establish your connection.  Most often the
solution is to add a command to the modem initialization string that
changes the way break signals are handled.

The Install program has a list of initialization strings for various
makes and models of modems.  Check for yours in the "Modem model"
section of the program.  If your modem is not listed, start by
choosing "Sierra Network Default Settings".  If that doesn't work
with your modem, try one of the two "Generic" switchless modems.

Some modems designed with Rockwell ROM chips have problems sending a
break signal due to the design of the control chips.  The two modems 
best known to exhibit this behavior are the Boca 14.4K internal Fax
modem and the Gateway Telepath internal 14.4K Fax modem.

Our programmers have designed an alternate modem driver that works
around this hardware problem.  While this replacement driver was
designed specifically for the Boca and Gateway modems, other 14.4K
internal fax modems that use a Rockwell chipset may benefit.  You
can choose this driver by selecting "Generic switchless (alternate)"
in the "Modem model" section of the Install program.


                 ERROR MESSAGES AND THEIR MEANINGS
                 =================================

ERROR #8 -
--------
The system that lets you reach out and touch TSN is busy at the 
phone number you chose during the installation process.  If you 
wait a few minutes and try connecting again, you should be able 
to get through.  If the number nearest you is busy on a regular 
basis, please call 1-800-743-7721 (between 8:00 AM and 10:00 PM, 
seven days a week) and report the busy port.

In the interim you can try calling another nearby access node, 
but YOU WILL BE RESPONSIBLE FOR ANY TOLL OR LONG-DISTANCE CHARGES.  
Run the Install program from the directory into which you 
installed TSN, choose "Access Phone #", and press F1 for a list 
of local access numbers.

ERROR #9 -
--------
If you cannot hear your modem pick up the phone and dial, the 
"COM Port" setting in the Install program may be incorrect.  
Check which COM port your modem is using, re-run Install and 
choose that COM port.

If you have an internal modem, and if you can hear the modem go 
off hook, dial, and connect, but you still get Error #9, try 
changing the COM port the modem uses.  If your modem is set to 
COM 2 or COM 3 try changing to COM 4. Check your modem manual for 
the proper switch settings or jumper positions to change the 
COM port on the modem.

ERROR #10 -
---------
The system that lets you reach out and touch TSN may be 
experiencing network trouble.  If the problem persists for more 
than a few minutes, call 1-800-743-7721 (between 8:00 AM and 
10:00 PM, seven days a week) and report the problem, including 
the number you are calling, so that we can get it fixed.  In the 
interim you can try calling another nearby access node, but YOU 
WILL BE RESPONSIBLE FOR ANY TOLL OR LONG-DISTANCE CHARGES.  Run 
the Install program in the directory into which you installed 
TSN directory, choose "Access Phone #", and press F1 for a list 
of local access numbers.

ERROR #12 -
---------
Your modem initialization string may need modification.  TSN works 
best if MNP 5 error correction is disabled.  If your modem is not 
on the list of modem models in the Install program and the default 
choice gives you this error, check your modem manual for the 
initialization command that disables MNP error correction.  While 
advanced modem commands vary, often this command is AT&Q0 or AT\N0.  
If you are unable to find the commands to disable MNP error 
correction please call TSN Tech Support at 1-800-743-7721 between 
8:00 AM and 10:00 PM, seven days a week.

ERROR #13 -
---------
The system that lets you reach out and touch TSN may be experiencing 
network trouble.  If the problem persists for more than a few 
minutes, please call 1-800-743-7721 (between 8:00 AM and 10:00 PM, 
seven days a week) and report the problem, including the number you 
are calling, so that we can get it fixed.  In the interim you can try 
calling another nearby access node, but YOU WILL BE RESPONSIBLE FOR 
ANY TOLL OR LONG-DISTANCE CHARGES.  Run the Install program in the 
directory into which you installed TSN and press F1 in the access 
number screen for a list of local access numbers.

ERROR #21 -
---------
Reconnection Failure can be caused by two conditions.  First, check 
your modem initialization line to make sure that the modem init 
string disables MNP error correction.  Second, if your modem has the 
Rockwell ROM chips you may need to use the alternate modem driver.  
If you are receiving this error and your modem does not appear on 
the modem model list in the Install program, please call 
1-800-743-7721 (between 8:00 AM and 10:00 PM, seven days a week).

ERROR #999 -
----------
This indicates that you have encountered an unknown problem and the 
system was unable to determine what went wrong.  This error message 
indicates that something unusual that the software cannot identify 
occurred on your system.  Check your system configuration for COM 
port conflicts and available memory.  If you have an external 
modem your serial cable may be defective.  Try switching serial 
cables and see if the problem persists.  If you continue to get 
this error please call 1-800-743-7721 (between 8:00 AM and 10:00 PM, 
seven days a week).

UNABLE TO LOAD VIDEO DRIVER -
---------------------------
This indicates that the LSCI.CFG file in the directory into which 
you have installed the TSN software has been damaged.  To fix this 
run the Install program, make sure the Video option is set correctly, 
and choose "Accept these choices".  This will re-write the LSCI.CFG 
file for the TSN software.
