VScom PCI Configuration
Installation guidelines for OS/2
Requirements:

A card of type VSCom PCI 200, 400, 800, 210, 100L, 110L, 200L, 210L, 400L or 800L is being used. Also certain versions of VScom PCI H-series may be used. You have the SIO.SYS driver downloaded.
All cards from the VScom PCI series may be used, if you install the actual SIO2k driver. Please read more about this in the section of Plug & Play configuration.

I. Manual configuration:
Procedure:

First of all, turn your computer off, insert the card in a slot and turn the computer on.

  1. The first step is to find the configuration of the card. You have to know the I/O addresses, IRQ, bus and device number of your card(s). To achieve this run VSSHOW.COM in a DOS window. This utility displays all VScom cards found in the system. Write down all data output by this program.
  2. If you posess a card from the L-series, please set the speed-jumper to "compatible". This is also possible with some products from the series PCI-H. Otherwise run the CONFPCI.EXE utility with following parameters:
    CONFPCI w <pcibus>:<device nr> MiscControl:2:2=1<return>
     Where:
    <pcibus> is the bus number output by VSSHOW.COM
    <device nr> is the device nr. output by VSSHOW.COM
    This command sets the default clock of the card to standard 1.8 MHz, so only max. of 115200 bps are possible. The reason is that the version 1.60d of SIO.SYS does not know about the higher clock, so it were possible to "overclock" the modem. But if you know, what you are doing, you can skip this step, so even higher baud rates are possible (14400 means than 115200, 28800 gives you 230400)
  3. Install the SIO software and modify the line with the SIO.SYS entry as follows:
    Device=<path>\sio.sys (COM1,3f8,4) (COM2,2f8,3) (COM3,<Vscom port 1 IO>,<VScom IRQ>) ....
    Device=<path>\vsio.sys
     This command makes standard com1 and com2 and all additional VScoms available to the operating system.
Example 1:
  1. VSSHOW.COM <return>
     Output:
    VS PCI 400 found at bus 0, device nr. 11 func 0
    IRQ = 12
    SPEED: HIGH
    Com port 1: 0xE800
    Com port 2: 0xE808
    Com port 3: 0xE810
    Com port 4: 0xE818
  2. In DOS window run:
    Confpci w 0:11 MiscControl:2:2=1 <return>
  3. In config.sys modify or include line like this
    Device=<sio path>\sio.sys (COM1,3f8,4) (COM2,2f8,3) (COM3,e800,12) (COM4,e808,12) (COM5,e810,12) (COM6,e818,12)
    Then reboot the system.
Example 2:
  1. VSSHOW.COM <return>
     Output:
    VS PCI 200 found at bus 0, device nr. 11 func 0
    IRQ = 12
    SPEED: HIGH
    Com port 1: 0xE800
    Com port 2: 0xE400
  2. In config.sys modify or include line like this
    Device=<sio path>\sio.sys (COM1,3f8,4) (COM2,2f8,3) (COM3,e800,12) (COM4,e400,12)
    Then reboot the system.
II. Automatic configuration:

You can use the program VSSHOW to configure your system automatically.

Procedure:
  1. as above
  2. as above
  3. Run VSSHOW as follows:
    VSSHOW siofile=c:\config.sys ports=<port list>
    Where port list is a list of numbers separated by comma. It instructs VSSHOW to use only those ports mentioned behind the equal sign. When this parameter was omitted ports 1 through 32 will be used.
    This command copies the config.sys onto config.org, looks for a line
    device=<path>\sio.sys ... and appends port definitions for VScom card.
Example:
  1. VSSHOW.COM <return>
    Output:
    VS PCI 400 found at bus 0, device nr. 11 func 0
    IRQ = 12
    SPEED:HIGH
    Com port 1: 0xE800
    Com port 2: 0xE808
    Com port 3: 0xE810
    Com port 4: 0xE818
  2. In DOS window run:
    Confpci w 0:11 MiscControl:2:2=1 <return>
  3. VSSHOW siofile=c:\config.sys ports=4,5,6,7
III. Plug & Play configuration:

The same author also provides a new driver named SIO2k. This driver locates PCI boards automatically, and detects the actual configuration. Furthermore it investigates the type of UART, and the maximum speed of the port.
This driver is released now. You find the version SIO 2k 2.01 on this CD-ROM. Also in this directory there is an extended control file, which includes all VScom PCI boards with serial ports. The official Distribution of the driver may be sent to everyone. The actual state is available at Gwinn.com.
