How to install PC/X non-intelligent board under SCO OpenServer:
* Driver is built into SCO.
* Only boards supported are PC/4 & PC/8 - PC/16 is not supported
* No other COM port or peripheral can share an IRQ with the DigiBoard
* PS/2 Models 25 & 30 can only be setup as COM2.

SCO Driver Installation for PC/X DigiBoard
1. Log on to the console, and type at the prompt
mkdev serial (press return)
2. The first screen you will see is:
The following cards are currently configured:
(any previous installed serial board will be listed)
i) install a new serial board.
r) remove an existing board.
q) quit
Please enter your choice (i/r/q) > (usually you are picking i)
3. Serial Board Installation
You would like to install a:
1. 1 port
2. 2 port
3. 4 port - if using PC/4
4. 5 port
5. 8 port - if using PC/8
6. 16 port - NOT SUPPORTED
Select an option or enter 'q' to quit: select 3 or 5
The card is configured as:
1. COM1
2. COM2
3. COM3 (not supported)
4. COM4 (not supported)
Select an option or enter 'q' to quit: select 1 or 2
4. Which card do you have (the following are supported) ?
(Pick you DigiBoard type from list shown on screen)
5. Please enter the baud rate to be used on the modem devices:
(pick highest baud supported by modem, example 9600)
6. The following /etc/gettydefs entries support 9600 baud lines
1. 9600
2. console
3. 9600H
4. o
5. 6
6. m
7. sc_m
Then you should see the following messages:
System files successfully updated.
The following standard serial devices have been installed.
(you will see a list of device names that will be created)
You must create a new kernel to effect the driver change you
specified. Do you wish to create a new kernel now? (y/n)
(answer yes to this question, then reboot system)
7. The systems will create devices in the /dev directory for the
DigiBoard PC/X, they will be created after system reboot.
Board setup Standard devices Modem control devices
COM 1 /dev/tty1a-tty1h /dev/tty1A-tty1H
COM 2 /dev/tty2a-tty2h /dev/tty2A-tty2H
Standard devices are usually terminals and printers.
These ports must have a null modem cable or null modem
adapter between the DigiBoard and the peripheral to work.
The basic cabling for x/on x/off flow control is TxD and
RxD crossed and signal ground straight through. Check your
DigiBoard hardware manual for proper cabling, if unsure.
Modem control devices are usually modems.
These ports must have carrier detect high before the port
will open. The cabling usually has signal going straight
from DigiBoard to modem. Check your DigiBoard manual for
proper cabling, if you have any questions.
8. How to enable standard port to get a login.
enable /dev/portname
example: enable /dev/tty1a
Make sure your terminal matches the setup in your inittab
file for SCO Unix or ttys for SCO Xenix.
The default is 9600 baud 8 bits no-parity 1 stop bit.
