Name
       lta - lta pseudoterminal interface

Syntax
       options LAT
       pseudo-device lat
       pseudo-device lta[n]

Description
       The  pseudoterminal  interface  provides  support  for local area transport (LAT) service.  LAT service allows users to access remote nodes
       through the Ethernet.

       To configure the LAT service for your machine, you must:

       o   Edit the system configuration file.

       o   Edit the file.

       o   Create LAT special files.

       o   Edit the file.

       Instructions for performing these tasks are further documented in the Guide to Ethernet Communications Servers.

   Edit the Configuration File
       Edit the configuration file  to	include  the  option  and  the	and  pseudo-devices.   The  configuration  file  to  edit  is  located	in
       /sys/conf/vax/HOSTNAME  or  /sys/conf/mips/HOSTNAME  (depending	on  your processor), where HOSTNAME is the name of your host processor, in
       uppercase.

       The optional value for the pseudo-device entry defines the number of LAT lines to configure, a number between 1 and 256.   If  you  do  not
       specify	a  value,  the	default is 16 lines.  For example, if you want to configure 32 LAT devices into your system, the entry for the LAT
       lines is:
       pseudo-device lta32

       To use the system as a load host for remote note maintenance functions such as loading and controlling  terminal  servers,  you	must  also
       include an options entry for and a pseudo-device entry for in the configuration file.

   Edit the /etc/rc.local File
       Edit  the  file	to restart LAT service automatically when the system reboots.  Add the following entry after the commands for local daemon
       startup:
       if [ -f /etc/lcp ]; then
	    /etc/lcp -s > /dev/console & echo -n ' lat' >/dev/console
       fi

   Create LAT Special Files
       Create the LAT special files by running the program from the directory and specifying the option.  You create one LAT special file for each
       LAT device.  For example, the following commands create 32 device special files for LAT devices:
       # cd /dev
       # MAKEDEV lta0
       # MAKEDEV lta1

       The option range is 1 to 7.  The maximum number of LAT special files is 256.

   Edit the /etc/ttys File
       Edit  the  file	to  include entries for all the LAT special files you created using the command.  For more information on how to add these
       entries, see
