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 1
Getting Started
893-386-B 1-1
The Model 3395/3395A Terminal Server is a combination of hardware and software that links users at
serial devices, such as terminals, to resources on both local area networks (LANs) and wide area networks
(WANs). These resources include a variety of hosts, workstations, and printers, as well as other SynOptics
terminal servers. You can use a terminal server to gain access to any of these hosts on the network:
• UNIX hosts that support the TCP/IP protocol
• International Business Machines (IBM) hosts that have a Telnet server
• DEC VAX hosts running ULTRIX that support TCP/IP
• DEC VAX hosts that support the Local Area Transport (LAT) protocol
When a user such as the one shown in Figure 1-1 makes a connection to a LAN host through the terminal
server, he can use all the resources on that host as if his terminal were directly attached to it.

The user in Figure 1-1 has made a connection to the UNIX host on the LAN through the terminal server.
He can now read databases, send mail, and run applications on this host. He can also connect to the VAX
host, the IBM host, or a serial device on the other terminal server.
Expanding the Network with the Terminal Server
The terminal server can support a variety of devices, other than terminals. These include printers, modems,
data switches, personal computers, and other host computers. These devices allow terminal server users to
access LAN resources in many different ways, and provide additional resources to LAN users. Figure 1-2
shows an example of a Model 3395/3395A Terminal Server on the LAN, with several different devices
connected to it.
Figure 1-2. A terminal server on an Ethernet LAN
In a network like the one in Figure 1-2, terminal server users can gain access to the hosts connected directly
to the LAN. Users on the LAN hosts can reach the devices connected to the terminal server, such as the
printer, the host system, or the personal computer.

The remaining sections of this chapter explain how you can use the terminal server in a network such as
this one. These sections include the following topics:
• Using the terminal server
• Logging on to a terminal server port
• Managing sessions
• If you make a mistake
• Privilege levels
• Summary
Using the Terminal Server
When you log on to the terminal server you make a connection with a terminal server port. A port is the
interface between a terminal and the other devices on the network, including hosts, printers, and other
terminal servers. Each port has a set of characteristics and privileges that determine how you can use it.
The network manager defines these characteristics and privileges with terminal server commands.
From the terminal server port, you can enter commands such as those described in Chapter 3 of this
manual. While the privilege level and the characteristics of your port determine which commands you can
use, most users can enter commands that do the following:
• Establish connections to devices on the network
• Display information about network destinations, and the characteristics of the terminal server port
• Modify some characteristics of the terminal server port
The Menu Interface
On some terminal servers, the network manager may have created a menu that overrides the terminal server's
command interface. The menu displays choices that you can select to establish connections on the network,
or change the configuration of your port. Chapter 2 describes the menu interface in more detail, but the
information described here about logging on and off the port and establishing sessions will still be useful to
you, even if you are using a menu.
Dedicated Services
The network manager can define a dedicated service at a terminal server port. If so, the terminal server
automatically connects the port to a host on the network when you log on to the port. While you might
not be able to use the terminal server commands in this manual if your port has a dedicated service, you can
read this chapter for general information about the terminal server.

Getting Started
1-4 893-386-B
Logging On to a Terminal Server Port
If your terminal is connected directly to a terminal server port, press the <Return> key until one of the
following prompts appears on the screen. If your terminal is connected to a host on the terminal server
network, log off of the host, or suspend your current session by pressing the <Break> key or the local
switch character. Then, press the <Return> key until one of these prompts appears and use the appropriate
procedure:
#Enter your login password and press the <Return> key. The default password on
many terminal servers is ACCESS, but the network manager may have defined a
different password for your terminal server. When you enter the correct
password, the Enter username> prompt appears.
Enter username>Enter your username and press the <Return> key. Your terminal server
implementation may require specific usernames. If not, you can enter any
username between 1 and 16 characters, or enter <Ctrl><Z> to automatically
assign the username PORT_xat this port, where x is your port number. When
you enter your username correctly, the TS3395> prompt appears.
TS3395> This is the default local command prompt, and it means that you are logged on
to a terminal server port. When you see this prompt, you can enter terminal
server commands.
Note: These are the default prompts that the Model 3395/3395A Terminal Server includes with the
terminal server software. The network manager can change these prompts, however, so the
prompts on your terminal server may be different.
Kerberos Passwords
Kerberos is an Internet network authentication service that may exist on your terminal server. It requires
that you enter a Kerberos password to gain access to the terminal server. The Kerberos password prompt
appears after the Username> prompt in the Model 3395 Terminal Server login sequence, and looks like this:
Enter user password>
If this or a similar prompt appears at your terminal, enter a Kerberos password.
Terminal Server Scripts
Some terminal server ports automatically execute a predefined set of terminal server commands called a
script when you log on to the port. The script may prompt you for a password, change some characteristics
of the port, or establish a connection with a host on the network. The information in this chapter will still
be useful to you, however, even if your port automatically executes a script when you log on.

Getting Started
893-386-B 1-5
Managing Sessions
The connection between a terminal server port and a device on the network is called a session. You can
establish a session with a LAT service, a Telnet host, an IBM host, or another terminal server after you log
in to the terminal server port. The Model 3395/3395A Terminal Server allows you to open several
sessions simultaneously, and move among them while you work. The next sections explain how to
establish and manage sessions.
Establishing a Session
Several terminal server commands establish sessions with LAN destinations, but the one you will probably
use most often is the CONNECT command. If you know the name or address of the device where you want
to establish a session, simply enter it with the CONNECT command at the prompt and press the <Return>
key:
TS3395> connect destination-name
If you are not sure of the names and addresses on your network, you can view a list of all the different
destinations on the LAN with the SHOW DESTINATIONS command. (Some of the destinations in this
list may be unavailable to you for security reasons. The network manager can tell you if this is the case.)
When you enter the SHOW DESTINATIONS command, a list similar to the following appears on the
terminal:
TS3395> show destinations
FINANCE.SUN.COM UNIX Host at 140.179.20.1
ACCOUNTSVAX VAX/VMS LAT SERVICE
PAYROLLHOST IBM Host
LASER2 Department Laser Printer
The first column on the list shows the names you can use in connect commands to reach a service or a
host. The second column displays information about each destination name, such as a description of a
service or the Internet address of a Telnet domain. The information in the second column may or may not
appear; the destination names in the first column are all you need to make a connection.
To establish a session with the Telnet host FINANCE.SUN.COM, for example, you could enter the
CONNECT command like this:
TS3395> connect finance.sun.com
TS3395 -010- Session 1 to FINANCE.SUN.COM established
Welcome to Finance.SUN.COM
Enter username:
You can also use the Internet address of a Telnet domain with the CONNECT command. Internet addresses
usually appear next to the domain names in the SHOW DESTINATIONS display or the SHOW
DOMAINS display.

Getting Started
1-6 893-386-B
Suspending a Session
When you suspend a session, you recall the Model 3395/3395A command interface without terminating the
connection to the remote resource. Later, you can reopen the session and continue with your work. To
suspend a session, press the Break key or the local switch character during the session. (A local switch
character is a control character sequence that you or the network manager can define. Chapter 2 explains
how to do this.) The TS3395> prompt appears, and you can enter any terminal server command, including
the CONNECT command:
$ <BREAK>
TS3395>
The next sections show how to use the RESUME command to reopen a previously suspended session.
Using Session Numbers
Each time you establish a session, the terminal server software assigns it a session number. The session
number appears in a display line right above the logon banner of the remote host. In the previous example,
the session number for the connection to FINANCE.SUN.COM was 1:
TS3395 -010- Session 1 to FINANCE.SUN.COM established
You can use session numbers with several terminal server commands when you switch among different
sessions, view the status of sessions, and disconnect from sessions.
Establishing Multiple Sessions
The terminal server command interface allows you to establish two or more sessions simultaneously. You
can then switch from one session to another without disconnecting from either of them. You can switch
sessions with terminal server commands, or define session switching characters for this purpose. Most
ports support up to four simultaneous sessions, and the network manager can enable a port to support up to
sixteen simultaneous sessions.
To establish a second session, suspend the current session with the Break key or the local switch character
and enter a connect command to establish the next session. You can then suspend that session and go back
to the previous session. The SHOW SESSIONS command displays all of your active sessions and their
session numbers. The display is similar to this one, for a user named Johnson, with three active sessions:
TS3395> show sessions
Port 12: Johnson Service Mode Current Session 2
- Session 1: Connected Interactive FINANCE.SUN.COM
- Session 2: Connected Interactive ACCOUNTSVAX
- Session 3: Connected Interactive PAYROLLHOST

Getting Started
893-386-B 1-7
To switch from session 2 at a LAT service to session 1 at FINANCE.SUN.COM, you could use a sequence
like this with the RESUME command, beginning at the LAT service:
$
$ <BREAK> FINANCE.SUN.COM session 1 resumed
Disconnecting From a Session
You can disconnect from a session in two ways. If you are currently logged on to a host or service, enter
the normal logoff command of the host or service. In this example, the user Johnson logs off of a UNIX
host:
% logoff
JOHNSON logged out at 25-AUG-1993 16:00:21.12
TS3395 -012- Session 1 disconnected from FINANCE.SUN.COM
TS3395 -101- 2 other session(s) active
TS3395>
When the host or service accepts your logoff request, the terminal server terminates the session. It also
displays a message that indicates if you still have active sessions.
If you are running the terminal server software because you have suspended a session, use the terminal
server DISCONNECT command from the TS3395> prompt. Enter the session number with the command,
and the terminal server will terminate the session:
TS3395> disconnect session 1
TS3395 -011- Session 1 disconnected from FINANCE.SUN.COM
TS3395 -101- 2 other session(s) active
TS3395>
Use the SHOW SESSIONS command to display active session numbers.
Using Other Terminal Server Commands
Many other terminal server commands are available to you, other than the session management commands
described in this chapter. These include HELP, SET PORT, LOCK, and several others. HELP provides
online information about all terminal server commands, SET PORT modifies the characteristics of your
port, including the functions of control characters, and LOCK prevents other users from gaining access to
your port while you are away. You enter all of these commands from the TS3395> prompt. Chapter 3
describes these and other commands in detail.

Getting Started
1-8 893-386-B
Using UNIX Aliases for Terminal Server Commands
The Model 3395 Terminal Server software provides several UNIX equivalents, or aliases, for Model
3395/3395A Terminal Server commands. If you work in a UNIX environment, you may want to use these
aliases because they will be more familiar to you than the Model 3395/3395A commands. Instead of the
terminal server HELP command, for example, you can enter the MAN command. Chapter 3 includes a
description of the UNIX aliases for terminal server commands.
Logging Out of the Terminal Server Port
The terminal server LOGOUT command logs you out of the terminal server port. When you do this, the
terminal server disconnects any sessions that are still active.
TS3395> logout
TS3395 -020- Logged out port 12 on server XFF4B15 at 22 September 1993
16:12:00
The log out message includes your port number and the name of the terminal server, as well as the date and
time you logged off.
If You Make a Mistake
Do not be concerned if you make a mistake, such as a typing error, when you enter a command. The
terminal server displays an error message and often some information that helps you correct the command.
In any case, you can reenter the command correctly, or recall and edit the command line with the editing
characters described in Chapter 2.
Privilege Levels
Privilege levels determine which terminal server commands you can use. The network manager can set the
privilege level at each port to one of three levels:
• Secure
• Nonprivileged
• Privileged
All the commands in this manual are available at Secure ports.
The two other higher privilege levels, Nonprivileged and Privileged, allow users to enter system
management commands, gain access to other users' ports, and alter the parameters in the terminal server
database. The Software Management Guide for the Model 3395/3395A Terminal Server describes the
Nonprivileged and Privileged levels in more detail, and Commands Reference for the Model 3395/3395A
Terminal Server describes all the commands available to users with these privilege levels.

Summary
The Model 3395/3395A Terminal Server provides you with access to many resources on the network that
might be unavailable to you otherwise. To use the terminal server, you log on to a terminal server port and
establish sessions with hosts or other terminal server ports. You can suspend sessions and establish new
sessions, so that you have several simultaneous connections. Terminal server privilege levels determine
which commands and command options you can use at a terminal server port.
The remaining chapters of this book include information that helps you use the terminal server. These
chapters include more details about the user interface, complete descriptions of the Secure level commands,
how to use the Multisessions feature if your terminal supports it, information about TN3270 connections,
and how to transfer files between a personal computer and a host through the terminal server.

Chapter 2
The User Interface
893-386-B 2-1
This chapter describes how to use the terminal server command interface and the terminal server menu
interface. It includes these topics:
• Entering commands
• Editing the command line
• Assigning session management functions to keyboard characters
• Session switching characters
• Telnet session management characters
• Using the terminal server menu
If your port has the Multisessions characteristic enabled, the user interface behaves somewhat differently
than the way this chapter describes it. See Chapter 5, “Using Multisessions Feature,” in addition to this
chapter for information about entering commands and using session management control characters in a
Multisessions environment.
Entering Commands
You enter commands at the terminal server prompt:
TS3395> COMMAND KEYWORD variable [KEYWORD variable ]. . .[[KEYWORD]
variable ]
Most terminal server commands allow you to enter two or more keywords and variables on the command
line. If you do this, separate each characteristic with a space, a comma, or a combination of both. You can
enter a command line that exceeds the line length of the screen as long as you do not press the <Return>
key until the command line is complete. The maximum length of a command line is 132 characters.
Abbreviating Commands and Keywords
You can abbreviate many terminal server commands and keywords to the shortest unambiguous string of
characters that the terminal server can interpret. For example, the CONNECT command begins with C, and
C is the only character you need to enter the CONNECT command. You could also enter CON or CONNE.
Each command description indicates whether or not you can abbreviate it. If so, the command description
lists the minimal number of characters that you can enter to execute the command.
Editing the Command Line
You can change, correct, or edit the command line before you press the <Return> key, or recall previous
command lines, with special keys and control characters. To use control characters, press the Control key
and the second character simultaneously. Table 2-1 lists these editing keys and the control characters that
come predefined with the terminal server software.
