1.  What driver should I install for my intelligent asynchronous Digi product? (PC/Xe, 
     MC/Xe, PC/Xi, MC/Xi, Xem, and PC/Xr ISA and PCI only)? 
     You may have received a diskette with your product which contains the current Windows 95 driver.  
     The diskette should be labeled as part number 40001841C.  If you did not receive this disk with your
     product, the current released driver is version 1.6.3 and can be downloaded from our web site.  The
     downloadable filename is 40001841C.exe.  Follow the install.txt for installation instructions.  
     NOTE: The complete path is: ftp.digi.com/support/drivers/win95/4001841C.exe.
     NOTE: This driver does not support EISA.  You can get the EISA driver at
     ftp.digi.com/support/drivers/win95/old/4000764P.exe

2.  How do I tell what version of the Windows 95 driver is currently installed? 
     Select Windows Explorer.   In the following path: WIN95, System select the digifep5.vxd file. 
     Select File, Properties.  A description will be displayed which includes a Version tab. 

3.  How can I tell if my Digi driver has loaded?
     Since Hyperterminal does not work with direct connect, use Digi's TTY program.  To verify that the
     ports are working, go to Digi's web site and download TTY.exe to test the ports: 
     http://ftp.digi.com/support/utilities/async/

     Run the executable and choose Settings.    Select the port you have connected the modem to. 
     Configure the communications settings to match the modem and choose OK.  Then choose
     Action, Connect.  You should be at a modem command prompt (you will see a blinking cursor). 
     To verify whether or not you are receiving a response from the modem, try typing AT and hit return
     to see if the modem will respond  with an OK.  This will show that the data was sent to the modem
     and a response was received back from the modem.

     If you do not have a modem, put the Digi loopback connector on the port.  At the command prompt,
     try typing.  The characters that you type within the terminal session should be echoed back to the
     console.  If you can see what you are typing, this shows that data is being both transmitted and
     received on the port.

     NOTE: It is possible to start two instances of TTY and test the ports by connecting them with a
     standard "NULL MODEM" cable.  Set each to the same baud rate, parity, and stop bits.  Try typing
     some characters in the active window.  If you see characters appearing in the opposite window,
     then the ports are communicating.

  
4.  What are the installation instructions for installing the PC/X and MC/X under Windows
     95? 
     The installation instructions are found in the pcx_win95.txt document.  This document may be
     downloaded from the ftp site.  For hardware setup instructions go to:

• http://ftp.digi.com/support/techsupport/nonunix/win95/pcxwinsupport.html

5.  When trying to access a port, the following error message is received: The specified
     memory address could not  be set. 
     Verify that the memory address chosen does not conflict with any other devices in the system. 
     Refer to available memory address (question #10) for additional suggestions on resolving this
     problem. 

6.  When trying to access a port, the following error message is received: The port could
     not be set to the specified I/O address. 
     Check the dip switch settings on the board.  Typically this error message indicates that the dip
     switch settings on the board do not match the I/O address chosen in the driver configuration. 

     Verify that the correct driver has been installed for the Digi product.  An incorrect driver will also
     cause this error message.  Verify that the I/O address chosen does not conflict with any other
     devices in the system. 


7.  When trying to access a port, the following error message is received: The port could   
     not be set to the specified IRQ.
      Verify that the IRQ chosen does not conflict with any other devices in your system. 

     Actually, it is not necessary to set an IRQ for your Digi product. 

     In order to disable IRQ for an ISA adapter with the Windows 95 driver, go into Control Panel,
     System, Device Manager, Resources.  There will be a choice listed as Basic Configuration 0. 
     Use the arrow to the right hand side of this selection to view the other choices.  Choose Basic
    Configuration 1.  You will notice the IRQ selections are removed.  Restart Windows 95. 

     In order to disable IRQ for a PCI adapter, Run regedit to access the Registry editor.  Step through
     the registry tree to the following branch: 

• HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Class\DigiAsync\000X. 
• Highlight the 000X key. 
• Add a new entry by selecting Edit on the menu bar, then New, String Value.  Give the new value a name of TimerPeriod with a string value of 50.  
  

8.  When re-installing the Windows 95 driver, the following error message is received: Could not find dginstl.dll. 
     Most likely the version of Windows 95 you are running is OSR2.  OSR2 has a known bug where it
     cannot locate the driver files without prompting the user for the path, even though the path is the
     same as previously entered for the driver's inf file. 

     Always type in the complete path.  Do not use the browse option.

      NOTE: If this were a fresh install, diginstl.dll would be the first file to be copied since it contains the
      installer code.   Re-entering the complete path to the driver files will resolve the problem. 


9.  The Digi product was originally installed under Windows 3.1 or Windows 3.11.  After
     upgrading to Windows 95 and installing the Windows 95 driver, upon reboot, the system
     stops on a blue screen. 
     There are residuals of the Windows 3.1 or Windows 3.11 driver still contained in the system.ini file. 
     The following describes how to remove the driver:

• Start the Digi board configuration program from the Control Panel.
• Remove each board from the Installed Boards box by clicking on the board, then clicking on the Remove button. 
• Click OK, and save the changes to the SYSTEM.INI file.  When asked if you want to restart Windows, click on the Don't Restart Now button. 
• Use Windows Notepad to edit the SYSTEM.INI file (this should be in your main Windows directory). comm.drv=comm.drv 
  NOTE: Substitute your Windows system path for c:\windows\system above, if appropriate. 
  EXAMPLE: c:\w31\system 
• Find the comm.drv entry in the [boot] section of the SYSTEM.INI file and change it from: comm.drv=C:\windows\system\dbcomm.drv to: comm.drv=comm.drv 
  NOTE: Substitute your Windows system path for c:\windows\system above if appropriate.
  EXAMPLE: c:\w31\system 
• Find the vrcd.386, vdbcd.386 and vuartd.386, entries in the [386Enh] section of your SYSTEM.INI file, and delete all three entries. 
• At this point, you have uninstalled the driver so it won't be loaded when you restart Windows.  

If you wish to delete the driver files from your hard drive, continue with the following steps: 

• When you installed the drivers, you were prompted for two paths: your Windows path, and a path where you wanted the Digi board software copied.
• If you elected to use the default path, the files were installed in C:\WINDOWS\DIGIBRD.  Whatever the actual path, the files placed in the directory include: README.TXT, DGCONFIG.EXE, DGCONFIG.HLP.  Delete all files from your Digi board directory and remove the directory. 
• Remove the following files from your SYSTEM directory: DBCOMM.DRV, DGCTRLPN.CPL, VDBCD.386, VRCD.386, VUARTD.386. 
• You may also delete the [LogPorts] and [DigiBoard] entries from SYSTEM.INI, and the [digiboard] section from WIN.INI. 

To remove the Windows 3.11 device driver, follow these steps: 

• Edit the system.ini file by deleting digierr.drv from the drivers=mmsystem.dll line. 
• From the [386Enh] section delete the device=digifep5.vxd and device=digixall.vxd lines. 
• Delete the entire [DigiFep5] and [Digi*] sections. 
  NOTE: the * represents a possible variable.
• Edit the win.ini file.
• Delete the [DigiBoard] section.
• Delete the c:\windows\digibrd subdirectory from your hard drive. 
• From the c:\windows\system directory you should delete the digierr.drv, digifep5.vxd, digixall.vxd, dgctrlpn.cpl. 
• From the program manager select File, Run, and select control.exe.  Running the Control Panel in this manner, will remove the DigiBoard icon. 
  

10.  When installing the Windows 95 driver, I am having trouble finding an available memory
       address. 
       Check your config.sys file.  If you have a DEVICE= EMM386.EXE line in your config.sys file, you
       must add an exclusion to this line for the memory range you are installing the board under. 
        EXAMPLE: For the PC/Xe (64K) installed at D0000h: DEVICE=EMM386.EXE X=D000-DFFF 
                            For the Xem installed at D0000h: DEVICE=EMM386.EXE X=D000-D7FF 
                            For the AccelePort/Xe (8K) installed at D0000h: DEVICE=EMM386.EXE
                            X=D000-D1FF 

                    If the system is an ISA machine, verify that shadowing has been disabled in the CMOS
                    setup for the memory range the Digi board is being installed in. 

                    If the system is an EISA machine, verify that the board has been configured in the system's
                    EISA configuration utility, and that the settings chosen in the ECU match the settings
                    chosen when the driver was configured.  Be sure that a Digi supplied EISA configuration
                    file was used. 

                   Verify that the memory address chosen does not conflict with any other devices in the 
                   system. 

                    If there are no known memory conflicts, shadowing has been disabled, and the exclusion
                    statement has been added to the EMM386.EXE device line in the config.sys file, run the
                    DOS diagnostics from a clean DOS boot disk for the Digi product to verify the hardware. 

11.   How do you set a virtual I/O and IRQ with the Windows 95 driver? 
       There is no virtual UART support with the Windows 95 driver. 

12.  How do you disable IRQ for a PCI adapter within the Windows 95 driver? 
       The Digi adapter can be configured to use polling mode instead of interrupts.  To configure the
        Digi PCI adapter to use polling mode, Run regedit to access the Registry editor.  Step through the
        registry tree to the following branch: 

• HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Class\DigiAsync\000X. 
• Highlight the 000X key.  Add a new entry by selecting Edit on the menu bar, then New, String Value.  Give the new value a name of TimerPeriod with a string value of 50. 
  

13.  How do you disable IRQ for an ISA adapter within the Windows 95 driver? 
       In order to disable IRQ for an ISA adapter with the Windows 95 driver:

• Go into Control Panel, System, Device Manager, Resources.  
• There will be a choice listed as Basic Configuration 0.  Use the arrow to the right hand side of this selection to view the other choices.  
• Choose Basic Configuration 1.  You will notice the IRQ selections are removed.  
• Restart Windows 95. 
  

14.  Ports appear to be available in Hyperterminal, but when attempting to access the ports
       there is no response. 
       There is a problem with selecting Direct Connect within Hyper Terminal.  The direct to COM
       options are only for ports using standard I/O and IRQ.  In order to use Digi ports with Hyper
       Terminal you must use the TAPI.  To do this, go into Control Panel, Modems, and choose Add. 
       Windows 95 will auto detect your modem on your Digi port.   Keep in mind that the Digi driver for
       Windows 95 must first be installed. 

15.  What options are available for testing the ports under Windows 95?
        Since Hyperterminal does not work with direct connect, use Digi's TTY program.  This utility can be
        downloaded from ftp.digi.com/support/utilities/win95.  The downloadable filename is tty.exe.  Run
        the executable and choose Settings.    Select the port you have connected the modem to. 
        Configure the communications settings to match the modem and choose OK.  Then choose
        Action, Connect.  You should be at a modem command prompt (you will see a blinking cursor). 
        To verify whether or not you are receiving a response from the modem, try typing AT and hit return
        to see if the modem will respond with an OK.  This will show that the data was sent to the modem
        and a response was received back from the modem.

       If you do not have a modem, put the Digi loopback connector on the port.  At the command prompt,
       try typing.  The characters that you type within the terminal session should be echoed back to the
       console.  If you can see what you are typing, this shows that data is being both transmitted and
       received on the port.

       NOTE: It is possible to start two instances of TTY and test the ports by connecting them with a
       standard "NULL MODEM" cable.  Set each to the same baud rate, parity, and stop bits.  Try typing
       some characters in the active window.  If you see characters appearing in the opposite window,
       then the ports are communicating.


16.  I am having problems getting my ISA adapter to work within Windows 95.
        You do not need to specify an IRQ for an ISA adapter under Windows 95.  First disable it and then
        try using the port.

        In order to disable IRQ for an ISA adapter with the Windows 95 driver:                              

• Go into Control Panel, System, Device Manager, Resources.  
• There will be a choice listed as Basic Configuration 0.  Use the arrow to the right hand side of this selection to view the other choices.  
• Choose Basic Configuration 1.  You will notice the IRQ selections are removed.  
• Restart Windows 95. 

 17.  I have the new Acceleport Xr 920 product.  How do I achieve speeds of 460.8 KBps or
        921.6 KBps? 
        Microsoft Windows 95 does not support baud rates of 460.8 KBps or 921.6 KBps. 
        One possibility would be to switch to the Windows NT environment. 


18.  If you install two identical modems in Windows 95 and then try to use the second
        modem with a 32-bit program that supports TAPI, the first modem may be used instead. 
       The problem occurs if both modems are identified and installed as the same model. 
       The registry entries for all modems that are installed in Windows 95 include a value called
       HardwareID.  When you install two identical modems, the HardwareID value is the same for both
       modems.  When this occurs, Windows 95 is unable to distinguish between the two modems and
       uses the one that was installed first.

       To work around this problem, remove the second modem and then reinstall it as a different model. 
       To do so, follow these steps: 

• In Control Panel, double-click Modems. 
• Click the second modem, and then click Remove. 
• Click Add, click the Don't detect my modem check box to select it, and then click Next. 
• In the Manufacturers and Models boxes, click a manufacturer and modem type that is compatible with your modem.  If your modem is not compatible with another modem, click Standard Modem Types in the Manufacturers box and click the model that matches the speed of your modem in the Models box. 

NOTE: If you choose one of the standard modems, you may not be able to use some of the advance features of your modem.  For example, the option to use data compression may not be available. 

• Click Next. 
• Click the appropriate port for the modem, and then click Next. 
• Click Finish. 

NOTE: This problem typically occurs when you install one modem to use with communication programs, and another modem to use for a different purpose, such as sending and receiving faxes.  If both modems are identical and are installed as the same model, both modems appear in the Modems Properties dialog box.  
EXAMPLE: if you install two Zoom VFP V.32 bis modems in Windows 95, the following modems are displayed on the General tab in Modems properties: Zoom VFP V.32bis and Zoom VFP V.32bis # 2.

19.  What modem do I select on my Windows 95 client when connecting through NetWare
       Connect with a Modem/Xem installed in my Novell server? 
       Copy the DIGIMDM.INF file from the Windows 95 driver to the C:\\inf directory
       and then reboot.   The Modem/Xem will now appear in the list of selectable modems on the
       Windows 95 client. 

20.  How do I print to ports above COM9 under Windows 95? 
       The Windows 95 print spooler is 16 bit, therefore printers are only supported on COMs 1-9.

21.  When configuring ports in Wildcat 5.0 should TAPI or the direct COM port name be
       selected? 
        In WCConfig, under node settings, select TAPI rather than the direct COM port name when
        configuring your ports with Wildcat 5.0. 

22.  How do I save my devices and system summary to a text file to send to support for
       troubleshooting? 

• First, go into Control Panel, Printers, and Add a new Printer.  
• Click Next, then select Local Printer and click Next. 
• From the list of Manufacturers, select Generic.  From the new list of printers displayed, select Generic/Text Only and click Next.  From the list of Available Ports displayed, select FILE, creates a file on a disk and click Next.
• Do not select this as your default printer, click Next.  Its not necessary to print a test page, click next and finish.
• A new printer icon for this printer will be displayed. 
• Now, go back to Control Panel, System, Device Manager and select Print. Select All Devices and System Summary but leave the Print to file checkbox clear.  
• Select Setup. 
• Select Specific Printer. 
• In the pulldown list a new option will be displayed Generic/Text Only on FILE:.  Select that and click OK, OK.
•  A window will display allowing you to select a name for this file.  Forward this file along with your case number to support@dgii.com.
