     NOTES ON CARBON COPY FOR WINDOWS 
     ================================
     This document contains important information about Carbon
     Copy for Windows including the following topics:

       *  Copying files from the Carbon Copy for Windows disks

       *  Information not found in the User Guide
  
       *  Using the SETCOM Utility (using COM3 or COM4)

     FILE TRANSFER PERFORMANCE
     =========================
     File transfer performance has been increased significantly 
     since the previous release of Carbon Copy.

     MODEMS NOT FOUND ON OUR LIST OF DESCRIPTORS
     ===========================================
     From time to time, there may be new modems released by various 
     manufacturers which are not included on our list of modems. 
     This is because these modems were not available to us at the 
     time that this product was released. In addition, there may 
     be updates to existing modem descriptors which have been made 
     since this product was released.

     If you are using a modem which does not appear on our list of 
     modems, you must call our Technical Support BBS at (617) 762-5134. 
     The BBS is available 24 hours per day, seven days a week. You may 
     use Carbon Copy Terminal, or any terminal emulation package to 
     dial the BBS. Configure Carbon Copy Terminal for Hayes 2400, and 
     configure the port settings to 8 data bits, no Parity and 1 Stop Bit. 
     This should get you connected temporarily to get the updated 
     modem file.

     There are five modem files included with this release of 
     Carbon Copy. The files are:
     MCMODEM.DSC - Modem file use with Carbon Copy for Windows 2.5
     MODEMS.DAT - Modem file used with Carbon Copy Terminal
     MODEMS.MLD - Modem file used with Carbon Copy Gateway
     MODINDEX.DAT - Modem file used with Carbon Copy Gateway
     CCDMODEM.DSC - Modem file used with Carbon Copy for DOS support

     You will find these files located under the Carbon Copy for Windows 
     menu on the Technical Support BBS. For additional assistance, please 
     contact our Technical Support staff at (617) 551-1414.

     USING THE LAN IPX DRIVER
     ========================
     Carbon Copy 2.5 has been significantly enhanced from earlier 
     versions of Carbon Copy. When connecting Carbon Copy 2.5 using 
     the LAN (IPX) driver, the remote PC must be running Carbon Copy 2.1 
     or later.


     CARBON COPY GATEWAY SERVER
     ==========================

     Installing Multiple Gateway Servers
     ===================================
     If you are installing multiple Gateway Servers on a network,
     the Server Name must be unique for each server. Use GATECFG.EXE 
     to configure the Server Name for each server.

     Running Applications on the Carbon Copy Gateway Server
     ======================================================
     Carbon Copy Gateway is a non-dedicated server that allows other 
     applications to run on the same PC. There are some applications that 
     may affect the PC's ability to function as a Gateway Server, such 
     as applications that are CPU intensive or applications that access 
     the serial port. Also, since the Gateway Server uses the network, 
     running applications on the Gateway Server PC that use the network 
     may also affect the PC's ability to function as a Gateway. 
     These are not limitations of the Gateway Server, but rather the PC itself.
     
     Running the Carbon Copy Gateway Server on IPX or NetBIOS Networks
     =================================================================
     Carbon Copy Gateway can be run on IPX or NetBIOS type networks. 
     To configure the Server properly, you MUST specify the .CFG file for the 
     network type. For example, at the DOS command prompt type either:
          GATECFG GATEIPX.CGF
               or
          GATECFG GATENETB.CFG

     Workstation Names with Underscores
     ==================================
     When calling into a Gateway Server, the workstation names 
     appearing in the listbox may have underscores. This is normal. 
     NCSI replaces spaces in the workstation name with underscores.

     CFG File Not Found
     ==================
     If the message "CFG file not found" is displayed when executing 
     GATEIPX, GATENETB, or GATECFG make sure the .CFG file is in the 
     same directory as the executables. If they are not in the same
     directory, expand the file off the Carbon Copy diskettes or 
     from an Administrative installation on a network. For more 
     information on expanding files, see the section "Copying Files
     from the Carbon Copy for Windows Disks" in this document.

     Increasing the NCBS Parameter
     =============================
     When using the Gateway on a NetBIOS compatible network, you should 
     increase the NCBS parameter on the Gateway Server PC as well as the 
     Carbon Copy workstation by 10. For example, if NCBS is currently set 
     to 10, increase it to 20. If you later install other applications 
     that use NCBS, be sure you increase this parameter again.

     If you plan to run Windows on the Gateway Server PC while the Gateway 
     is in memory, you should add the following line to the [386Enh] 
     section of the Windows SYSTEM.INI file:
     COMXBUFFER=3200
     Where X is the serial port for which the Gateway is configured. 

     CARBON COPY TERMINAL
     ====================
     Carbon Copy Terminal fully supports baud rates up to 115200. 
     However, the Windows serial port driver does not support 
     baud rates above 57600. To use Carbon Copy Terminal at a 
     baud rate of 115200, an enhanced serial port card with a 16550 UART
     and a communications driver that supports 115200 must be installed.


     COPYING FILES FROM THE CARBON COPY FOR WINDOWS DISKS
     ====================================================
     The files on the Carbon Copy for Windows installation disks are 
     compressed. The files are not usable until they are expanded. 
     Setup expands the compressed files as they are copied onto 
     your hard disk.

     If you need to copy files directly from a Carbon Copy for Windows disk
     without using Setup, follow these steps:

       1. Copy EXPAND.EXE (located in the \INSTALL directory) from the
          Carbon Copy Setup Disk onto your hard drive. (This utility expands
          compressed files to a usable format.)

       2. Insert the disk with the file you want to expand into drive
          A: (or any floppy-disk drive).

       3. Type the following and press ENTER:

             EXPAND A:path\<filename> C:<filename>

          where A: is the disk drive you are copying from (source)     
           C: is the disk drive you are copying to (destination)

          The compressed file is expanded as it is copied onto your
          hard-disk drive.


     INFORMATION NOT FOUND IN THE USER GUIDE
     =======================================

     Using Carbon Copy with Novell NetWare
     -------------------------------------         
         The following minimum versions of Novell NetWare components
         are recommended for proper operation when using the Carbon 
         Copy LAN (IPX) driver:

             Windows Components
             ------------------
             NETWARE.DRV:    v2.02 (021026)
             NWIPXSPX.DLL:   v1.32
             NWPOPUP.EXE:    v2.02 (021027)
             VIPX.386:       v1.13 (920903)
             VNETWARE.386:   v1.06 (921015)

             DOS Components
             --------------
             EMSNETX.EXE:    v3.31 (921112) 
             IPXODI.COM:     v2.00 (920904)
             LSL.COM:        v2.00 (920904)
             NETX.EXE:       v3.31 (921112) 
             TBMI2.COM:      v2.10 (911204)
             XMSNETX.EXE:    v3.31 (921112) 

         It is especially important to update to Novell's VIPX.386
         version 1.13 or later.  The version that ships with Windows
         3.1 will not work properly.

         The latest files are available on CompuServe in the Novell forum as
         WINUP9.ZIP and DOSUP9.ZIP.  Later versions of these files
         may be available and may be used also.


     Using Carbon Copy with 3COM 3C505 LAN Adapter Cards
     ---------------------------------------------------   
         The 3COM 3C505 LAN Adapter card does not work properly
         with Microsoft Windows in enhanced mode.  3COM is
         working on new drivers that will correct this problem.
         Contact 3COM technical support at (800) 876-3266 for
         more information.


     LAN (IPX) Setup Connect Timeout
     -------------------------------
         Connect Timeout within the LAN (IPX) Setup dialog
         represents the number of seconds allowed before an
         attempted connection is terminated.


     Disabling the Host Video on 256-color Cards
     ------------------------------------------- 
         Carbon Copy may not be able to disable the video on some 256-
         color cards. Changing to a 16-color driver will usually 
         correct this.


     Windowing a 256-Color DOS Application
     -------------------------------------
         Microsoft Windows reports that it is unable to display your
         256 color DOS application in a window when using a 256
         color display driver.  Carbon Copy for Windows will not be
         able to remotely control Windows at that time. When
         running with a 16 color driver, however, Windows will 
         emulate the 256 color DOS application (in 16 colors).
         Carbon Copy for Windows, in this instance, can successfully
         control Windows running the windowed application.


     Display Drivers
     ---------------
         The Windows display drivers not directly supported by
         Carbon Copy for Windows include the following:

          Olivetti/AT&T monochrome or PVC display
          Quad VGA
          82c441 VGA


     Replacing COMM.DRV with CCCOMM.DRV
     ----------------------------------- 
         You may need to replace COMM.DRV with CCCOMM.DRV 
         when running Windows in Standard Mode. If you experience
         a toggle in DTR that causes the connection to drop when you 
         open a DOS box or exit Windows, replace COMM.DRV with 
         CCCOMM.DRV in your SYSTEM.INI file. To replace COMM.DRV with
         CCCOMM.DRV, you must first copy CCOMM.DRV to the WINDOWS\MICROCOM
         subdirectory. Then, open your SYSTEM.INI file in any text editor
         and locate the line COMM.DRV=. Edit that line as shown in 
         this example:
         COMM.DRV=C:\WINDOWS\MICROCOM\CCCOMM.DRV 
         Where WINDOWS is your Windows directory.

     Diamond Stealth VRAM 1280 16-color Mode
     --------------------------------------- 
         The Diamond Stealth card will not work with Carbon Copy
         in this mode, but it will work with other modes such as
         1024x768 16 or 256-color modes.


     XGA 16-color, HP 16-color SVGA
     ------------------------------
         These cards do not work with Carbon Copy in 16-color mode
         using their native drivers.  However, they will work fine
         using the Windows standard VGA driver.  The XGA and HP
         cards also work correctly with native drivers using any of 
         their 256-color modes.


     ATI Mach32 Setup Failure to Install Drivers
     -------------------------------------------
         On some system configurations when running Windows with
         an ATI Mach32 driver, Carbon Copy for Windows Setup will
         fail to properly install required drivers.  This may occur at the
         end of setup when it states that it will install drivers and 
         restart Windows.  If Windows does not restart, change your current
         directory to the directory you chose to install Carbon Copy for
         Windows in and type 'CCWCOPY'.  This batch file will install
         the required drivers.  After the batch file is complete, Carbon
         Copy is fully installed.  Restart Windows to use Carbon Copy
         for Windows.


     ATI Ultra/Mach32 "Crystal Font" Driver
     --------------------------------------
         The ATI Ultra/Mach32 "Crystal Font" driver does not work
         properly with Carbon Copy, however, all other ATI Ultra/Mach 32
         drivers work fine, including 1024x768 and 256-color drivers.
         If you are using this driver, use the Windows Setup program to
         select another Ultra/Mach32 driver, and then reinstall Carbon Copy.


     Network Warning Messages During Windows Startup
     -----------------------------------------------
         Carbon Copy is not able to display Network Warning
         messages during Windows startup.  In order to prevent
         problems with remote control, we recommend disabling
         these messages using the Network option in Windows
         Control Panel.  If these messages are not disabled, you
         will not be able to view the Host screen until the dialog
         box is removed.  However, the keyboard is still active
         and pressing <Enter> will remove the warning message.


     Using Window's Standard Mode with the LAN (IPX) Driver
     ------------------------------------------------------
         The TBMI2.COM utility must be loaded before Windows
         can be run in standard mode using the network. If you get
         a "Communication driver in not installed" message, make
         sure that this utility is loaded before you start Windows.

         TBMI2.COM is required by Novell if running Windows in 
         Standard mode. If running DOSHOST, TBMI2.COM should 
         be loaded after DOSHOST.


     Increasing Performance on 80286-based PCs
     -----------------------------------------
         Most 80286-based machines running at 12-MHz or slower
         will give better performance if the port speed is set at 9600
         baud or lower.  Using port speeds greater than 9600 baud may
         actually decrease throughput on these machines due to more
         frequent retransmissions.

         If you are running Windows version 3.1, you may use the
         FasterModeSwitch=1 option in the [standard] section of your
         Windows SYSTEM.INI file. Enabling this setting causes
         Windows running in standard mode to use a faster method of
         switching from protected to real mode on many 80286-based
         computers. When this setting is enabled, Windows responds
         quicker to hardware interrupts, screen updates, and improves
         file transfer speeds. NOTE: This setting has no effect on 
         80386-based computers. Some early IBM AT and compatible
         computers do not support this setting. Enabling this setting on
         these 80286-based machines may cause them to lock up when
         starting Windows.


     ISA Cornerstone Set to "Optimize for Photographs"
     -------------------------------------------------
         The Cornerstone driver has a problem displaying
         highlights when set to "Optimize for Photographs". This
         will result in some of Carbon Copy for Windows dialogs,
         including some in Setup, to not display selected options.
         To solve this, use Cornerstone's Control Panel applet to
         set the driver to "Optimize for Speed".


     Enhancing Mouse Performance
     ---------------------------
         When using Carbon Copy for Windows with modems that
         connect at 2400 baud, mouse performance can be enhanced
         by changing the QuickMouse parameter in CCW.INI as follows:

               QuickMouse=5

         This change must be made directly using a text editor. 
         (CCW.INI is located in your WINDOWS directory.)  The
         default setting of QuickMouse=2 is best for modems that
         connect at baud rates of 9600 or higher.

         When using modems that have asymmetrical modulation
         schemes, the transmit and receive channels may operate at
         vastly different speeds.  An example of such a modem is the
         US Robotics Courier HST.  For these modems, you may want
         to set QuickMouse as high as 10 for best performance.

         You may also notice better performance by setting
         QuickMouse to a higher value on noisy phone lines.


     Disconnecting with the "Exit Windows" Dialog Displayed
     ------------------------------------------------------
         Because of a limitation within Microsoft Windows, you
         should not disconnect from a Host machine while the
         "Exit Windows" dialog is displayed.  If you do, you may
         not be able to reconnect to the Host system until
         someone at the host machine responds to the dialog box.


     Changing the Communications Options
     -----------------------------------
         If you change any of the options on the Communications
         menu (i.e. change drivers, WorkStation Name, Port, etc.)
         while DOSHOST is loaded, you should unload and reload
         the DOSHOST program.  Some of the options do not take
         effect in DOSHOST until this is done.

     Running Setup with Limited Disk Space
     -------------------------------------
         Setup requires a minimum of 4Mb of disk space plus 2Mb
         of temporary workspace to install the complete Carbon Copy
         for Windows product.  If your disk space is limited to less
         than this amount, and you have a previously installed version
         of Carbon Copy for Windows on your hard disk, you may want
         to delete it so you have enough space to reinstall the product.


     Using Carbon Copy along with CPU Intensive Applications
     -------------------------------------------------------
         When using Carbon Copy utilities such as File Transfer or 
         Remote Control, along with CPU intensive applications 
         (mostly benchmark programs), the Carbon Copy utility
         may sometimes display the message "General Failure", or 
         lock-up your system. This means that File Transfer is not 
         receiving enough CPU time to do its work. If this happens, 
         simply close the application that is causing the problem 
         and try to run the Carcon Copy utility again.
          
         If you have trouble connecting to a machine that is running
         this type of program, you may want to try terminating the
         application before attempting a connection.


     Changing the Mouse Settings during Remote Control
     -------------------------------------------------
         If you change the mouse settings in the Windows Control
         Panel during a remote control session, the Guest's mouse
         may temporarily be out of synchronization with the Host
         mouse. If this happens, simply use the keyboard to choose
         the OK button in the Mouse Settings dialog, and the mouse
         will return to normal.

         Note that there is very little reason to change the mouse
         settings on the Host in this way.  Mouse performance is
         mostly affected by the Guest's mouse settings.

     Microsoft Mouse 9.0 Pointer Growth Option
     -----------------------------------------
         Microsoft Mouse (Software Version 9.0) pointer growth
         option should not be enabled on the Guest when running
         remote control. This may cause the cursor to change to
         an hourglass randomly.

     HP Intellifont Drivers
     ----------------------
         The HP Intellifont display driver (IFW.DRV) is
         incompatible with Carbon Copy for Windows.  You should
         remove this driver from your SYSTEM.INI in order to use
         Carbon Copy.  


     Communications Port Not Found Message
     -------------------------------------
         If you get a "Communications port not found." message
         from Carbon Copy, you may want to check the "Custom"
         settings in the Port Settings dialog box to make sure
         they are correct.  The settings installed by using the
         "Default" pushbutton are usually correct for most systems.


     LAN Connections using Routers without IPX Message 14h Support
     -------------------------------------------------------------
         Some routers do not pass IPX message type 14h.  Carbon
         Copy for Windows uses, as a default, message type 14h
         to establish connections over LANs.  When using the
         routers without this support, Guests and/or Hosts will
         not appear in the Call a Host dialog.  To solve this
         potential problem, enter the line:
     
                NetwareBroadcast=On

         in the [Carbon Copy] section of CCW.INI.  CCW.INI can
         be found in your Windows directory.


     Using Carbon Copy with Asynchronous Communications Servers (ACS)
     ================================================================

         See ACS.TXT for application notes regarding the use of
         Carbon Copy with NCSI/NASI and EBIOS/INT14-based ACS
         products.

     Using Carbon Copy with NETBIOS
     =============================
         See NETBIOS.TXT for application notes regarding the use of
         Carbon Copy on a NETBIOS compatible network.


     USING THE SETCOM UTILITY (USING COM3 OR COM4)
     =============================================

         In many systems, Windows will not recognize serial
         ports COM3 and COM4.  See SETCOM.TXT for information
         about the SETCOM utility and solutions to this problem.


     FILES INCLUDED ON THE DISKETTES
     ===============================

         See FILELIST.TXT for a list of files included on the diskettes.
