4. The confirmation screen lists the values you have selected. The following text appears on the screen (default values are
shown):
You have chosen the following setup
The tty prefix is ttyl.
The printer prefix is prnl.
Number of Multi_View pseudo devices [user-specified number].
If these values are correct, type Y and the installation process will continue. If there is an error in any of the values
displayed, type N and the first screen displays. Then re-enter the information for each card.
When you accept the confirmation list (by typing Y), a series of messages displays while the driver is being installed and
the kernel rebuilt. After the terminals have been added to the Terminal Control database, and when the display says
Press <Enter> to continue:, then press ENTER. When Installation complete displays, press
ENTER again.
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
OR
Type init 6 and press ENTER .
Driver installation for the ISIHP card now is complete.
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 ISI3334 card loads successfully. If the firmware for any ISI3334
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 ).
