CHAPTER 8 LAT NETWORK CONFIGURATION
8-7
ULTRIX Configuration
Operation of the print server under ULTRIX is similar in concept to VMS
in that you must create a LAT application port and associate a print queue
with that port (note that ULTRIX can alternatively be configured with
TCP/IP as described in Chapter 2). This procedure requires system manager
privileges and is shown in the following sections.
1. Verify that LAT is working. This can be done simply with a LAT-
compatible terminal server; by doing a
SHOW NODE
or
SHOW
SERVICE
command, you should see the name of your ULTRIX host
displayed. If you do not have a terminal server available, execute the
following command:
lcp
-c
This command displays the LAT traffic on the network. You should
minimally see some number of frames transmitted because your ULTRIX
computer periodically broadcasts messages across the network. If LAT is
not working, first check your cabling and your network configuration. If
LAT still does not work, then you may need to install LAT into your
system. This is a fairly complex procedure that requires rebuilding your
kernel; refer to your ULTRIX documentation for information on this
procedure.
2. If you have not already done so, create some LAT devices. This is
done by first changing your default directory to
/dev
and then use
the
MAKEDEV
command to create 16 LAT devices:
cd /dev
MAKEDEV lta0
This will create 16 devices numbered sequentially. For example, it will
create tty00 through tty15 if you have not previously created any terminal
devices. To create an additional 16 devices, type:
MAKEDEV lta1
3. Edit the /etc/ttys file to add a line similar to the following for each LAT
connection:
tty05 "etc/getty std.9600" vt100 off nomodem
#LAT
(substitute your actual tty number in place of "tty05").
4. Verify that you have created valid LAT tty devices with the command:
file /dev/tty* | grep LAT
Valid LAT devices will have a "39" in the description that is printed
when this command is executed.
