About this Guide

4DLT™ is a Silicon Graphics' implementation of Local Area Transport (LAT™), network protocols originally developed by Digital Equipment Corporation (DEC™) that optimize communications between terminal users and network hosts. 4DLT enables Silicon Graphics workstations to participate in a LAT network.

4DLT software performs LAT terminal server functions in a Silicon Graphics workstation, allowing a user to connect to the LAT network from his or her workstation. 4DLT software also enables a Silicon Graphics workstation to supply its resources to other LAT network users.

Purpose of This Guide

The 4DLT User's Guide explains how to use 4DLT software to connect to LAT network nodes and use the services they offer. The audience for the 4DLT User's Guide are IRIS users who need to access LAT network resources from their workstations. This guide assumes readers are new to LAT but have experience with resource sharing on networked systems.

Organization of This Guide

The 4DLT User's Guide is organized into these chapters:

Chapter 1, “Notes to New Users,” 


introduces concepts and terms that apply to LAT networks. Read this chapter to learn how a LAT network is organized and how 4DLT functions in the network.

Chapter 2, “Starting Work with 4DLT,” 


explains SLAT, the 4DLT utility that supports your connections to the LAT network. Use this chapter to start and stop SLAT and to prepare for using the commands described in Chapter 3.

Chapter 3, “Using SLAT Commands,” 


describes the commands available to you when you are running SLAT. It explains the purpose of each SLAT command and shows you how to use it. Use this chapter as a learning aid and reference guide to SLAT commands.

Typographical Conventions

This document uses the standard UNIX® convention when referring to entries in IRIX manual pages. The entry name is followed by a section number in parentheses. For example, cc(1) refers to the cc manual entry in Section 1 of the IRIX manual pages.

In text descriptions, file and directory names, as well as commands, are shown in italics. Command syntax descriptions follow these conventions:

typewriter font

Indicates a user entry. Type these entries, or portions of entries, exactly as shown.

<Enter>  


Indicates a key legend on the workstation keyboard.
