INSTALLING QUADPORT IN THE SCO UNIX OS 

Revision 1.0 4/9/97

This document describes in detail the steps necessary to install the Axxon Quadport 16554 I/O
card in the SCO Unix OpenServer 5 environment. Installation procedure for earlier releases of 
SCO Unix OS should be similar.

1) Power down computer system. Remove cover to computer system. Install the Axxon Quadport
hardware into a vacant 16 Bit ISA/EISA bus slot. Secure this card with a mounting screw.

2) Power up system using a DOS boot diskette. The control software for the Quadport is for use
in a DOS environment. Run the QUADPORT.EXE software to configure the Quadport hardware.
Once the Quadport hardware is saved, this control software is not required for normal operation.
The configuration values are statically saved to the Quadport hardware.

The Quadport hardware can either :

a) Replace your existing COM1 serial port and provide a total of  4 Serial ports in this place.
b) Replace your existing COM2 serial port and provide a total of  4 Serial ports in this place.

Case #1 - Installing Quadport under the COM1 label

i) Turn OFF your present COM1 by setting the appropriate jumpers or changing the CMOS
values for your motherboard. In addition, you cannot have another device occupying IRQ 4.

ii) The ports on the Quadport will be indexed as - tty1a (Port #0); tty1b (Port #1); tty1c (Port #2);
tty1d (Port #3). The lower case labels reflect a serial port WITHOUT modem control. 

iii) Respectively, these ports will also be indexed as - tty1A (Port #0); tty1B (Port #1); tty1C
(Port #2); tty1D (Port #3). The upper case label  denotes  a serial port WITH modem control.

Select "Manual Configure" option in the QUADPORT.EXE software to configure :

Port #0 : I/O Address 0x0290..0x0297    IRQ : 4
Port #1 : I/O Address 0x0298..0x029F    IRQ : 4
Port #2 : I/O Address 0x02A0..0x02A7    IRQ : 4
Port #3 : I/O Address 0x02A8..0x02AF    IRQ : 4
Also, ACTIVATE the IRQ Pending Register to : I/O Address 0x02D0. Save the settings.


Case #2 - Installing Quadport under the COM2 label

i) Turn OFF your present COM2 by setting the appropriate jumpers or changing the CMOS
values for your motherboard. In addition, you cannot have another device occupying IRQ 3.

ii) The ports on the Quadport will be indexed as - tty2a (Port #0); tty2b (Port #1); tty2c (Port #2);
tty2d (Port #3). The lower case labels reflect a serial port WITHOUT modem control. 

iii) Respectively, these ports will also be indexed as - tty2A (Port #0); tty2B (Port #1); tty2C
(Port #2); tty2D (Port #3). The upper case label  denotes  a serial port WITH modem control.

* Reference : Page 340 of SCO OpenServer Handbook.

Select "Manual Configure" option in the QUADPORT.EXE software to configure :

Port #0 : I/O Address 0x0190..0x0197    IRQ : 3
Port #1 : I/O Address 0x0198..0x019F    IRQ : 3
Port #2 : I/O Address 0x01A0..0x01A7    IRQ : 3
Port #3 : I/O Address 0x01A8..0x01AF    IRQ : 3
Also, ACTIVATE the IRQ Pending Register to : I/O Address 0x01D0. Save the settings.

3) Power down the computer system to force a hardware reset. If necessary, remove the
Quadport product and install into the target computer system running SCO Unix. You may
pre-configure the Quadport on a different system. Power up the computer system.

4) Login to the SCO Unix environment for system maintenance. Ask your supervisor for details
on the required passwords.

5) Enter the following :

#mkdev serial      ; will display the current serial port settings

Typical display (SCO does not support COM2 in the default install) :

1. IBM-COM1   1 port card   i/o address = 3f8, interrupt = COM1

Assuming, we wish to add the Quadport product under the COM2 label, proceed as follows :

i)nstall new serial board
r)emove an existing board
q)uitPlease enter your choice (i/r/q) > i           ; to install the Quadport

Do you want to install a :

1. Standard tty device

Enter your choice or q to quit : 1             ; we do wish to install a tty device

You would like to install a :

1. 1   port card
2. 2   port card
3. 4   port card    (Select for the Quadport product)
4. 5   port card
5. 8   port card
6. 16  port card

Enter your choice or q to quit : 3             ; select 3 for a 4 port card

The card is configured as :

1. COM1
2. COM2 (for this example - select this option)
3. COM3
4. COM4

Enter your choice or q to quit : 2             ; as originally intended

Which card do you have (the following are supported) ?

(List of mfrs to vary with your version and build of SCO Unix)

Enter your choice or q to quit : 4   (Or other value for STARGATE model)
* The Axxon Quadport hardware mimics the DIGI STARGATE product

Please enter the baud rate to be used on the modem device : 38400   ; Or a lower baud rate to suit

The following /etc/gettydefs(F) entry supports 38400 baud lines :

1. o

Choose one of the following entries or q to quit : 1           ; to accept the above relationship

Rebuild the kernel and the environment to record the above changes.

Reboot SCO Unix and use.
