Preface
893-386-B xi
This manual describes how to use the Model 3395 Terminal Server on an local area network (LAN). It
explains how to use terminal server commands, and how to tailor some terminal server characteristics to
suit your needs. This manual is for people who want to use the terminal server to gain access to resources
on the network, rather than the individual who installs and manages the terminal server hardware and
software.
The network manager at your site decides how the network is set up and how much access you have to
network resources. Because of this, your system may respond differently from what this manual indicates.
Follow the instructions in this manual and use the descriptions as an example of what can happen in
response to the commands described here.
Organization
This manual contains the following chapters:
Chapter 1 Describes the purpose of the Model 3395 Terminal Server in a local area network (LAN),
and how to get started using terminal server commands.
Chapter 2 Describes the terminal server command interface and menu interface. This chapter
describes how to use command-line editing keys, and how to use control keys for session
management.
Chapter 3 Describes terminal server commands available at secure ports.
Chapter 4 Explains how to use a terminal during a TN3270 session.
Chapter 5 Explains the Multisessions (Dual Session Management) feature.
Chapter 6 Describes how to transfer files between personal computers and hosts through the
terminal server.
Conventions
Throughout this manual, the word “Enter” means type something and then press the <New Line>,
<Return>, or <Enter> key; for example, “Enter the CONNECT command” means type the word
CONNECT and then press the <New Line>, <Return>, or <Enter> key.

This manual also uses the following conventions:
COMMAND REQUIRED [OPTIONAL] [ optional ]
Where Means
COMMAND You must enter the command, or its accepted abbreviation, as shown.
REQUIRED You must enter a keyword, or its accepted abbreviation, as shown.
[OPTIONAL] You have the option of entering this keyword or variable. Do not type the [optional]
brackets; they only set off what is optional.
Additionally, this manual uses certain symbols in special ways:
Symbol Means
TS3395> This is the Model 3395 Terminal Server prompt at ports with the Secure and
Nonprivileged privilege levels.
$This is the Digital Equipment Corporation (DEC) VAX/VMS prompt.
%This is the UNIX C shell prompt.
In examples, this manual uses
This typeface to show your entry and responses and screens from the
Model 3395 terminal server.
This typeface to show responses from remote hosts and devices on the
network. This typeface also shows command keywords or arguments that
are variable, such as “hostname.”
