3.14.5 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.
Enter the number of ISA cards you want to install
and configure on your system (0-4):
Select 0 (zero) 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 ISIHx-2S or -2U card installed
• Specify 16 for each ISIHP-4S or -4U card installed
• Specify 8 devices for each ISIHP-4SD card installed
For example, if the computer contains three ISIHP-4S cards, you would enter 48.
The ISIHP-1S card is a special case. In the MultiTech Installation Script, you should specify 8 pseudo
devices for the ISIHP-1S card. However, only four of these pseudo devices will actually be used. The first
pair, ttyl1A and ttyl1B, will be used as terminal adapters; the third pair, tty11E and tty11F, will be used as
modems. (In device names like ttyl1A, the fourth character is a lower-case “L”; the device names are,
however, case sensitive.) The remaining ports (the second pair and the fourth pair) are not used and can
be allocated to a different purpose after the ISIHP-1S installation is complete. You must initialize each of
the four ports separately using the enable command (for example, enable ttyl1a).
The ISIHP-4SD is also a special case. In the MultiTech Installation script, you should specify 16 pseudo
devices for the ISIHP-4SD card. However, only the first 8 devices (ttyl1A through ttyl1H) will be used and
these will be used as terminal adapters. The remaining ports (ttyl1J through ttyl1P) are not used and can
be allocated to a different purpose after the ISIHP-4SD installation is complete. Use the enable command
to initialize ports.
