1. Introduction

      The VxCard Driver 2k is designed for the VXC Multi-port series
   cards. It creates COM ports for each card in Windows 2000/XP/2003. 
   Users can then use  standard  Win32 APIs (for example: CreateFile, 
   CloseHandle,  ReadFile, WriteFile...) to access the  COM ports of 
   the VXC cards.

   ********************
   A. COM port mapping by COM-Selector:
      VXC card equips a DIP switch to act as a Board ID and COM port 
   number selector.  If the Board ID is 0, the VxCard Driver defines
   the  COM port number to a valid one  on the system automatically. 
   When the Board ID is not 0, the VxCard Driver uses the "Board ID" 
   to be the first COM port number  and uses the "Board ID +1" to be 
   the second COM port number, and so on. (See appendix section.)
   
      The Max. COM port number is up to COM256.

   ********************
   B. Utility :
      The VxCard Utility shows all COM ports on the system, and let
   you to change the software FIFO size for each port.
   
   ********************
   C. Software FIFO Size:
      The standard serial port driver allocates 4KB buffer for each
   COM port, while the VxCard Driver allows user to have 128KB FIFO
   for each COM port. Users can use the VxCard Utility to modify it.

   ********************
   D. Plug & Play supported:
      The VxCard Driver 2k supports PnP in the Windows 2000/XP/2003.



2. Installation

       Please install the driver package before you plug-in the VXC 
   cards into the system. Then the system can recognize the VXC cards 
   automatically and simplify the installation procedures.

   A. Install the dirver's setup program. It will installs the Plug and
      Play information files, VxCard Utility program and kernel driver 
      files into the system.
      
        default folder:
        	C:\Program Files\VxCard2K   ==> for all files
        	
        	C:\WinNT\inf                ==> for inf files with oemxxx prefix
        	C:\WinNT\Systems32\Drivers  ==> for all driver files
   
   B. Configurate the COM port number by using COM-Selector (dip switch)
      first. See section 1.A and Section 3.
      
   C. Power off your cmoputer and plug the VXC card into an available
      slot.
      
   D. Power on your computer.
   
   E. In Windows XP/2003, it requires more PnP steps. Please select the
      "Install the software automatically" item to finish it when the 
      "Found New Hardware Window Wizard" pops up.

Note: 
   1. It's recommended don't use COM1 ~ COM4, since the COM1 and
      COM2 are usually reserved by systems, while the COM3 and COM4 
      may be used by other Plug&Play serial ports in the future. 
      
   2. Few software recognize the standard COM ports only. If your 
      software have problem to use the VXC Card COM ports, please 
      set the COM-Selector to zero (COM port number is auto-assigned) 
      and try the new COM port number again.

   3. After changing the COM-Selector, you have to uninstall the VXC 
      card from the Device-Manager, and then scan the new hardware
      to install the VXC card again (or re-boot the computer). This 
      forces the VXC card driver to read the new COM-Selector setting 
      and assigns correct COM ports for this card.

   4. For more information, please refer to the user's manual.
