5. Select Host and press ENTER . Remove the diskette from the drive.

6. Select Exit and press ENTER .

7. To reboot the system (required), enter the following commands:

• Type shutdown -g0-y and press ENTER

• Type init 6 and press ENTER .

Driver installation for the ISIHP card now is complete.

3.14.7 Activating Ports in SCO Open Server 5

SCO Open Server 5 provides a device database that monitors the activity of serial ports through which users

can log onto the host. If your ISI ports are used by terminals (e.g., to allow users to log onto your host), you

must create an entry in the system’s device database that furnishes specific information for the terminals that

will be used on each ISI port. The database is referenced each time a user attempts to log in. If there is no

database entry for a particular terminal, access to the host is denied.

1. Turn on your system and verify that the firmware for each ISIHP loads successfully. If the firmware for a

given ISIHP or ISIHI card does not load, none of its ports will be accessible. (If this happens, see

Multi-

Tech’s Administrative Utility

section in this manual.)

2. Type the complete name of the first device you want to create in usr/lib/uucp/Devices. Substitute the

specific base name, board number, and port letter for the generic parameters in the expression ttylbx.

Use a lower-case x value for local DTE (terminal) support and an upper case X value for modem control

for each port you want to enable. Example: ttyl2A denotes the second ISI card (2) and the first port on

that card (A). The port status can be altered later, but one setting must be selected at this time. The ACU

line would read as follows:

ACU ttylbX - 9600

dialer name

. Replace b, X and dialer-name with appropriate values.

3. Repeat this process for each port on each board you have installed. Record the setting you select for

each port.

4. Using device names created in the previous section, type the following command for each port you want

to activate: enable ttylbx

5. Repeat this command for each port you want to activate, using the lower case letter for local terminal use

or upper case for modem control.

Note: Only one of the options (e.g., modem control or local terminal access) should be enabled for any port at

one time. For example, you cannot enable ttyl1a and then enable ttyl1A. To change the status of a port,

disable the current status (disable ttyl1a) and then enable it for the desired status (enable ttyl1A).

3.14.7 Removing the Driver (SCO Open Server 5)

To remove the Multi-Tech Serial Card Driver, enter the configuration utility (e.g., custom for SCO Open Server

5) and follow instructions to remove the entire driver and rebuild the kernel without the ISI driver. If it is

necessary to reinstall the driver due to I/O address or IRQ overlap, remove the driver first.

Note: Remove the driver before permanently removing the ISI card from the computer.
