ISI5634PCI/4/8 User Guide
MultiTech Installation Script
The Multi-Tech Installation Script for SCO Open Server 5 systems requests information about how many
boards you want to install, designations for communication ports and printer ports, and how many pseudo
devices you want to create for Multi_View utility. Based on this information, the appropriate driver files
will be installed and linked with your system’s kernel.
1. This text appears on the screen:
You can install up to 4 ISA/PCI cards in a system. The PCI cards will be
autodetected on bootup [ISI5634PCI is a PCI card, i.e., it has a PCI bus].
Enter the number of ISA cards you want to install and configure on your
system (0-4):
Select 0 if your computer has a PCI bus. This tells the SCO operating system to autodetect the ISI
cards.
2. The following text appears on the screen:
Multi_View is a utility which will allow you to have multiple sessions on
terminals that have multiple pages of physical memory. In order for this
utility to work with MultiTech’s serial cards, pseudo devices have to be
created in your /dev directory. These devices are system-wide resources.
Enter the number of pseudo-devices to be created for the use of Multi_View
utility
(1 - 256).
The Multi_View utility initializes the multiple-page capability of terminals with multiple pages of
memory. The number specified here is the total number of devices (between 1 and 256) available to
all Multi-Tech terminals and it’s the number of pseudo devices available to the Multi_View utility.
Specify 8 pseudo devices for each ISI5634PCI-8 card installed;
specify 4 devices for each ISI5634PCI-4 card installed.
For example, if the computer contains three ISI5634PCI-8 cards, you would enter 24.
3. This text appears on the screen and relates to the “/dev” directory.
This script also creates the devices in your system to communicate with
the ports of ISICOM. The default prefix for the tty ports is ttyl. The
default prefix for the printer is prnl. Is this acceptable? (y/n/q).
For most users, it’s best to select y, which entails accepting the default values. Then proceed to
step 4.
Details for use of non-default port/printer values. The /dev directory holds device-information files
used by the kernel to access the hardware. When you add an ISI card, you must give the ISI ports
unique names so they do not conflict with existing ports or with other devices known to your system.
If a device name has already been assigned to an existing device and the operator assigns that
name to a new device, then the existing device will be deleted when the ISI port using its name is
created.
a. To use a non-default base name, type N and then enter a basename having less than five
characters. The base name you select will be used for all ports on each card you install. ISI port
designations will have this form:
[basename prefix][board number][port letter].
basename: Length is one to four characters.
board number: Values will be 1, 2, 3, or 4, depending on how many ISI cards are installed in
your computer.
port letter: For ISI5634PCI-4, use letters A through D for modems. For ISI5634PCI-8, use
letters A through H for modems. (For terminal control devices, use lower-case
letters as port identifiers.)
