Device Driver for SCO™UNIX®
Software Installation Documentation
Scope
Use this reference card to install the Hostess® device driver software and controller board
hardware. This device driver can support up to four of the following Comtrol Hostess
controller boards:
•Hostess 550 2-port
•Hostess 550 4-port with 100-pin or RJ45 connectors
•Hostess 550 8-port with 100-pin or RJ45 connectors
•Hostess 550 16-port
To use this device driver, you must have the SCO UNIX operating system installed on an ISA-
or EISA-bus machine. The installation follows these general steps:
1. Remove existing Comtrol drivers. (Recommended.)
2. Install the device driver.
3. Configure and install the controller board.
4. Configure and attach the interface box (if applicable).
5. Enable the ports on the controller.
Note: For more information, see the hardware documentation for your controller board and
interface box.

Removing the Device Driver
Follow these steps to remove an existing device driver:
1. Boot the system, log in as the system administrator to root, and invoke the custom utility.
2. Select the Remove option and press Enter.
3. Select Hostess 550 Device Driver and press Enter.
4. Select the Hostess 550 Device Driver package and press Enter.
5. Select Yes to verify the removal. Press Enter.
6. Type yto boot the kernel by default. Press Enter.
7. Type yto rebuild the kernel environment, then Enter.
8. The following message is displayed:
Setting up new kernel environment
Press any key to continue.
9. Select Quit and press Enter.
10. Select Yes and press Enter.
Note: Make sure that custom properly removes the old device driver before performing
step 11.
11. At the system prompt, type the following:
rm /etc/perms/h550 (Press Enter.)
12. Reboot your system. The device driver is removed after the kernel is rebooted.

Installing the Device Driver
Two device drivers for the SCO UNIX operating system, sio and pa, come installed in the
system and cannot be removed:
•sio (serial I/O device)
IRQ3 - reserved for the second communications port
IRQ4 - reserved for the first communications port
•pa (parallel I/O device)
IRQ7
The sio driver is configured to use interrupt vectors 3 and 4. You can reserve one of these
vectors for the controller only if the corresponding communication port is not installed in your
system.
Unless the pa driver can be removed from the kernel, or its interrupt vector can be changed,
interrupt vector 7 cannot be used by the controller.
Use the following procedure, which is based on the SCO UNIX operating system (3.2.4) to
install the device driver:
1. Boot the system, log in as the system administrator to root, and invoke the custom utility.
For more information about custom, see your system documentation.
2. Select the Install option and press Enter.
3. Select the A New Product option and press Enter.
4. Select the Packages option and press Enter.
5. Insert the device driver diskette into the floppy drive and press Enter.
6. Select the device driver to install and press Enter.
7. Select Continue. (The disk is already in the drive.)
8. Select the number of ports on the controller (4, 8, or 16) and press Enter.

9. Enter the base I/O address of the controller (in hexadecimal) and press Enter.
10. Enter an unused interrupt vector number for the controller and press Enter.
Note: The device driver may suggest an IRQ that is in use. If you choose an existing IRQ,
the system may allow you to change it.
11. Enter yor nto verify the configuration.
You will then be asked if you want to configure another controller board. Repeat steps 9 -
11 for each controller (maximum 4). Type nand press Enter when all of the controllers are
configured.
The following message is displayed:
The UNIX Operating System will now be rebuilt.
This will take a few minutes. Please wait.
12. Type yto boot the kernel by default. Press Enter.
13. Type yto rebuild the kernel environment, then Enter.
14. The following message is displayed:
Setting up new kernel environment
Press any key to continue.
15. Select Quit and press Enter.
16. Select Yes and press Enter.
17. Remove the driver diskette from the floppy drive.
18. Power off your system.
After the device driver is installed, use the appropriate tables in the following sections to
configure the controller. The configuration is based on your selection during the device driver
installation. For additional address settings, see the documentation that came with your
controller.
Note: Install the controller board after you set the DIP switches. Do not change the DIP switch
settings while the board is in the computer and powered up.

Configuration
Power up and reboot the system.
After you reboot the system, the following message should be displayed:
Hostess 550 Board Setup
Copyright (c)19xx Comtrol Corp. All Rights Reserved
Immediately following this message, each Comtrol controller found in the system is listed in
this format:
Hostess 550 board at xxx IRQ#has yports starting at ttyhzz
where xxx is the base address, #is the interrupt vector, yis the number of ports, and ttyhzz
is the name of the first port on the controller.
When installation is complete, use the following information to enable the ports.
Enabling Ports
The following table shows the default device names assigned to each non-modem and modem
serial port on the controller board:
The non-modem names allow communications with a serial device over a simple 3-wire
connection consisting of the transmit and receive data data lines and signal ground. The
modem names require modem control to function properly. Specifically, the carrier detect
Device Names
Controller Non-Modem Modem
First ttyh00-ttyh15 ttyH00-ttyH15
Second ttyh16-ttyh31 ttyH16-ttyH31
Third ttyh32-ttyh47 ttyH32-ttyH47
Fourth ttyh48-ttyh64 ttyH48-ttyH64

signal must be present before the serial port will become active.
Once the controller is found, you can enable the individual ports using the enable command.
Consult your system documentation for further information on the enable command. The
following example enables port ttyh00 and appends the changes to the /etc/inittab file:
enable ttyh00
With the device driver installed and the communication ports enabled, the controller is now
ready for use.
