    I. The TranXit Install Program
  
    1. Modifications to .INI Files

    The following changes will be made to your .INI files if you install
    TranXit using all the default conditions during the install program.

      a. Additions to SYSTEM.INI 
      
         [386Enh] section:  device=C:\TRANXIT\PCOMM2.386
                            device=C:\TRANXIT\PUMAIR.386
                            device=C:\TRANXIT\pumairtp.386 (IBM Think Pads only)

         [boot] section:    drivers=printpro

         [drivers] section: printpro=c:\tranxit\printpro.drv

      b. Addition to PROGMAN.INI
      
         [Groups] section:  Groupn=C:\WINDOWSDIR\TRANXIT.GRP

      c. Additions to WIN.INI 
      
         [ports] section:   TRANXIT2.PRN=
    

    Note: If you install TranXit on your computer more than once, previous
          instances of PCOMM2.386 will be commented out of SYSTEM.INI.  
          Only the most recent installation directory will be reflected in 
          SYSTEM.INI.

    II.  Installing TranXit with Remote Install

    To install TranXit on a remote computer that does not have
    a floppy drive, you can use the Remote Install option from
    the Options menu.  (The Remote Install menu item may be greyed
    if there is already a version of TranXit on the remote computer,
    and it is running.)

    When using the Remote Install feature, the remote computer must
    not be running SHARE.EXE.  This may cause transmission failure
    during the install process.  The remote computer must also be
    operating from the DOS prompt.  If you are running Windows(TM), you
    must exit Windows.  A Windows DOS box cannot be used.

    If you experience transmission problems during remote install, the 
    transfer baud rate may be adjusted in TRANXIT2.INI. In the [Advanced]
    section modify the following line:

        RemoteInstallBaud=57600

    Valid baud rates are: 2400, 4800, 9600, 19200, 38400, 57600, 115200. Try
    using a slower baud rate when you encounter transmission errors.

    III.  Trouble Shooting

    1.  Parallel Cable Connection

    If you have configured TranXit to communicate over a parallel cable, 
    and you do not get a New Window button (this is enabled when a 
    connection is established), check the following:

        a.  Make sure the that both the local and remote computers have 
            selected a parallel cable connection in Connection/Setup.

        b.  If the connection is intermittent, make sure the cable is securely
            fastened to the parallel port.

        c.  Verify that there are no conflicts with other hardware devices such
            as sound cards or network adapters.  The default IRQ setting for many 
            sound cards is IRQ 7.  This is also the IRQ that is used for 
            communication over LPT1.  Consult your adapter documentation for 
            changing the default IRQ on these boards.

        d.  If you have selected LPT2, the default IRQ on the I/O communication
            adapter may not be set to IRQ 5.  Try selecting IRQ 7 from the
            Change Connection Settings in the Connection Setup dialog box, or
            consult the I/O adapter documentation for changing the IRQ for
            LPT2 to IRQ 5.  If you have a bus mouse, it may be set to IRQ 5.
            If the mouse freezes after configuring TranXit for LPT2, there is
            an IRQ conflict. Consult your mouse hardware documentation for 
            changing the default IRQ.

        e.  If your computer has more than one parallel port, make sure the 
            cable is attached to the correct port.  Don't laugh, this is 
            a common oversight.

        f.  When connecting to a slower computer, Pentium to 386, you may need
            to start TranXit on the slower computer first.

        g.  The parallel cable must be LapLink(R) compatible and have male 
            DB-25 connectors at both ends. If you are not using a LapLink 
            parallel cable, make sure the cable is configured with the 
            following pin connections:
  
                25 Pin             25 Pin 
                -------            -------
                Pin 2     <--->    Pin 15 
                Pin 3     <--->    Pin 13 
                Pin 4     <--->    Pin 12 
                Pin 5     <--->    Pin 10 
                Pin 6     <--->    Pin 11 
                Pin 15    <--->    Pin 2 
                Pin 13    <--->    Pin 3 
                Pin 12    <--->    Pin 4 
                Pin 10    <--->    Pin 5 
                Pin 11    <--->    Pin 6 
                Pin 25    <--->    Pin 25 (Ground-Ground) 
  

    2.  Serial Cable Connection

    If you have configured TranXit to communicate over a serial cable, and 
    you do not get a New Window button (this is enabled when a connection 
    is established), check the following:

        a.  Make sure the that both the local and remote computers have selected
            the proper serial cable connection in Connection/Setup. The baud 
            rate setting must be the same on both systems.

        b.  If the connection is intermittent, make sure the cable is securely
            fastened to the serial port.

        c.  Verify that there are no conflicts with other serial devices.  
            Conflicts will occur when serial devices are sharing interrupts 
            (IRQ's).  In a standard configuration (if you computer is 
            equipped with 4 serial ports), COM1 and COM3 will share IRQ 4, 
            and COM2 and COM4 share IRQ 3. If your mouse is on COM1 and you're 
            trying to connect TranXit over COM3, there will be an IRQ conflict.  
            In this case, your mouse may freeze and you will not make a 
            connection with the remote computer.

        d.  If your computer has more than one serial port, make sure the cable
            is attached to the correct port.  

        e.  When connecting to a slower computer, Pentium to 386, you may need
            to start TranXit on the slower computer first.

        f.  The serial cable must be LapLink compatible, and can be either a 
            9-pin or a 25-pin female connector on both ends. If you are not 
            using a LapLink serial cable, make sure the cable is configured 
            with the following pin connections:
  
                9 Pin           25 Pin              25 Pin          9 Pin 
                ------          -------             -------         ------
                Pin 5           Pin 7     <--->     Pin 7           Pin 5 
                (Ground-Ground) 
                Pin 3           Pin 2     <--->     Pin 3           Pin 2 
                (Transmit-Receive) 
                Pin 7           Pin 4     <--->     Pin 5           Pin 8 
                (RTS - CTS) 
                Pin 6           Pin 6     <--->     Pin 20          Pin 4 
                (DSR - DTR) 
                Pin 2           Pin 3     <--->     Pin 2           Pin 3 
                (Receive-Transmit) 
                Pin 8           Pin 5     <--->     Pin 4           Pin 7 
                (CTS - RTS) 
                Pin 4           Pin 20    <--->     Pin 6           Pin 6 
                (DTR - DSR) 

        g.  Some notebook computers use the Windows loadable device driver 
            POWER.DRV for power conservation. If you are experiencing trouble
            connecting to a remote computer, and you have tried all of the 
            above steps, set the Power Management list box setting in the 
            Power Control Panel Applet to "Standard" or "Off."


    3.  Infrared Connection

    If you have configured TranXit to communicate with an infrared 
    connection, and you do not get a New Window button (this is enabled when 
    a connection is established), check the following:

        a.  Make sure the that both the local and remote computers have selected 
            the proper infrared connection in Setup/Connection.

        b.  There must be no obstacles blocking the line of sight between
            the infrared adapters.
    
        c.  The adapters should be placed away from any light or 
            electromagnetic source. These can include such items
            as wireless headphones, halogen desk lamps, and even
            computer monitors.

        d.  When connecting to a slower computer, Pentium to 386, you may need
            to start TranXit on the slower computer first.

        e.  Some notebook computers use the Windows loadable device driver 
            POWER.DRV for power conservation. If you are experiencing trouble
            connecting to a remote computer, and you have tried all of the 
            above steps, set the Power Management list box setting in the 
            Power Control Panel Applet to "Standard" or "Off."

        f.  If the message "Error establishing connection. Please verify 
            the port settings in connection setup." appears, it is possible
            that the infrared device could not be initialized properly. Restart
            TranXit after checking the following:

                -   Make sure the correct infrared model has been selected
                    in connection setup.
                -   If using an infrared dongle connected to the serial port, 
                    make sure the cable is securely fastened to the serial port. 
                    If the dongle requires an external power source, insure 
                    the power source is properly attached.
            

    4.  Workgroups For Windows/16550 UART

    Some computers equipped with the 16550/16550a UART chip may experience hangs when
    loading TranXit or running setup/connection within TranXit.  If you are using
    Workgroups For Windows, you must get an updated version of SERIAL.386.  This VxD
    will reside in the Windows SYSTEM directory ( i.e., C:\WINDOWS\SYSTEM\SERIAL.386).
    The update is available on CompuServe or from Microsoft's technical support.

    IV.  Other Issues

    1.  Clipboard Transfer

    When transferring graphics images from one computer's clipboard to 
    another, keep in mind that one of the clipboard formats 
    used is the DDB (Device Dependent Bitmap).  As the name implies this 
    format is dependent on the type of video display being used. 
    Problems may develop when images are transferred from a 16-color 
    display to a 256-color display or vice-versa.  A warning message 
    will appear when the format may not transfer correctly from one 
    computer's clipboard to another.

    If you are running TranXit 2.0, connected with a remote computer running
    TranXit 1.x, clipboard functions will be disabled.

    2.  Synchronization

    When synchronizing files between two computers, and selecting to copy 
    only files that are newer, for instance, TranXit compares the time stamps
    on the files on both computers and copies the files with the latest time 
    stamp.  This may cause the wrong files to be transferred if the internal 
    clock in the computers are not in sync.

    If you have selected synchronize options to copy only files that are newer,
    or older, be aware of time differences between the two computers. The following
    scenario may cause unwanted results when the file C:\BIN\FRED.BIN exists
    on both computers:

        -   Local Computer -- Date 1/1/91, Time 1:00:00.
        -   Remote Computer -- Date 1/1/91, Time 2:00:00.
        -   Modify FRED.BIN on the local computer (time stamp 1:05:00).  
            This is now the newer file of the two files, although, the time
            stamp on the file is older than the one on the remote computer.
        -   Synchronize  C:\BIN [Local]  <<  C:\BIN [Remote].
        -   Select options, copy only newer files.
        -   Begin synchronization.

        FRED.BIN, from the remote computer, will overwrite FRED.BIN on the 
        local computer because the time is newer (2:00:00). If the times
        on the two systems were the same, there would be no overwrite of
        the file.  

        TranXit will display a warning message when the first new remote
        window is opened if the time difference between the computers
        is greater than 1 hour.

    3.  Direct Infrared Printing

    In order for direct infrared printing to operate correctly, the following
    must be true:

        a. The item "Use Print Manager" in Control Panel / Printers, must
           be turned off.

        b. The item "Fast Printing Direct to Port" in Control Panel / Printers
           / Connect, must be turned off.

        c. The mode, in TranXit2 / Setup / Connection... / Setup 
           Connection..., must be set to "variable".

    4.  Problems with TranXit2 and other programs doing modem transfers
    
    When TranXit enables a link (e.g. parallel, serial, or infrared) to 
    establish a connection to a remote system, it is possible on some 
    systems to encounter difficulties when downloading data with another 
    program via a modem. This can happen even without the TranXit user 
    interface loaded if the PrintPro print redirection feature is 
    enabled. If you experience problems with modem downloads disable all 
    connections in Connection Setup in the TranXit user interface for the 
    duration of the download.
