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. Windows For Workgroups/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 Windows For Workgroups, 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. _________________________________________________________________ TranXit and TranXit2 are trademarks of Puma Technology, Inc.
