    1. The TranXit Install Program
   	
    The Tranxit for NT installer will make several additions to the 
    registry. If IR is selected as the default connection type then 
    the serial device will be disabled.  To change these settings 
    refer to the help file under 'using a serial cable' or 'using an 
    infrared device'.
  
    2. Installation

      Infrared

    During the TranXit NT installation, the user is presented with 
    the ConnectionSetup dialog box.  If s/he chooses "Infrared" and 
    selects a port, the file LEIR.INI is created in the user's 
    TranXit directory.  This file will show which port the user 
    specified to enable infrared capability.  This port name will 
    be a section heading in this file.

      Sample contents of LEIR.INI:

     [COM2]
        .
	.
     Enabled=YES
     Devices=device_name
	.
	.

    The installation searches for section headings COM1 through COM9.  
    If the heading exists, it searches for the line "Enabled=YES".  
    If it is successful in finding this string, the installation 
    makes appropriate entries in the Registry, initializing the 
    Infrared settings to Automatic and the Serial settings to Manual.  
    Then, it searches for the line "Devices=device_name" in LEIR.INI.  
    If it finds this line, it uses the device_name as the section 
    name to search for in INFRARED.DAT, which is also found in the 
    user's TranXit directory.

    In INFRARED.DAT, the device_name section is found.  Under this 
    section, there will be an entry "PhysDrv=irda_driver_name".  
    This irda_driver_name denotes the oem-specific irda driver that 
    the user has selected during connection setup.

    This irda driver is then copied from the user's TranXit directory 
    to the SYSTEM32\DRIVERS directory as IRDA_PHY.SYS.

      Serial

    If the user chooses Serial during connection setup, the file 
    LESERIAL.INI is created in the user's TranXit directory.  
    This file contains the name of the com port the user has 
    specified for serial capability.  The installation searches for 
    section headings COM1 through COM9.  If the heading exists, it 
    searches for the line "Enabled=YES".  If it is successful in 
    finding this string, the installation makes appropriate entries 
    in the Registry, initializing the Serial settings to Automatic.


      Uninstallation

    The uninstallation removes all the registry entries the 
    installation has created.  In addition, it sets the Serial 
    settings to Automatic in the Registry.

    II.  Trouble Shooting

    1.  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 your 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."

          h. For further instructions refer to the section 'Using 
             a serial cable' in the online help.	


    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 adapter connected to the serial 
                  port, make sure the cable is securely fastened to 
                  the serial port. If the adaptor requires an external 
                  power source, insure the power source is properly 
                  attached.

          g.  For further instructions refer to 'Using an infrared 
              device' in the online help.   

    _________________________________________________________________

   III.  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.

    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 1/1/93, Time 1:00:00.
     -   Remote Computer -- Date 1/1/93, 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.  Problems with TranXit and other programs doing modem transfers
    
     When TranXit enables a link (e.g. 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.  If you experience problems with 
     modem downloads disable all connections in Connection Setup in 
     the TranXit user interface for the duration of the download.

    4.  Long Filename Support

    Windows NT long filenames are not visible from TranXit's
    file window.

    If both computers are running TranXit and Windows NT, when
    copying files locally or between two computers, the Windows NT long
    file names are preserved. When copying files from a computer 
    running Windows 3.1 to a computer running Windows NT, you are 
    prompted to select the target computers file name if the existing 
    file has a long file name. You are given the option of retaining 
    the Windows NT long file name or use the standard Windows 3.1 
    (DOS 8.3 naming convention) file name. If you select the standard 
    Windows 3.1 file name, the long file name is destroyed. If File 
    Replace confirmations are disabled, the long file name will be 
    used, and you will not be prompted to select the target file name.
              
    5.  Connecting to previous versions of TranXit.

    This version of TranXit supports legacy connections with all 
    previous versions of TranXit with . It also supports connections 
    using the Infrared Data Association (IrDA) Standard.

    The default for TranXit is to support connections to TranXit 
    versions  2.00, 2.01 and 3.0. In this mode, TranXit will also 
    connect to most devices which support the IrDA Standard. If you 
    believe that you have TranXit configured correctly for a Variable 
    Mode infrared connection, but still experience difficulty 
    connecting to a device which supports the IrDA Standard:

      1. Edit the PUMAIR2.INI file in the TranXit install directory.
      2. Change the "TranXitLegacyMode" setting in the [IrDA Infrared 
         Driver] section from "Yes" to "No."
      3. If the systems still do not connect, see the Infrared 
         subsection of the Troubleshooting section in this file for 
         more suggestions.
      NOTE: If you change the "TranXitLegacyMode" setting to "No", you 
      will have to change it back to "Yes" to connect to legacy 
      versions of TranXit (2.00 and 2.01).

    6. Connection Setup

       In Connection Setup, you CAN specify the connection type as "serial" or "IR."  
       However, you CANNOT change the COM Port of the connection type within 
       the Connection Setup screen.  This must be specified during the initial installation 
       of TranXit, and cannot be changed once the program is installed. In order to change 
       the COM Port for each connection type, you need to reinstall TranXit.
