Chapter 3 - Software Installation
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 ISIHx-2S/2U, use letters A through D for TAs; use letters E
through H for modems. For ISIHx-4S/4U, use letters A through H
for TAs; use letters I through P for modems. (For terminal control
devices, use lower-case letters as port identifiers.)
Device basename selected: _____________________________________
b. After you select a device basename, you are prompted for a printer base name. This
prefix identifies each port that supports a terminal with a printer attached to its auxiliary
port (for transparent printing). Specify a unique printer base name (printer parameters
are outlined in the Multi_Setup Utility section in this manual ).
Printer base name selected: _____________________________________
When you have specified the device base name and the printer base name, press
ENTER to continue.
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.
