Introduction

About This Guide

About TN5250
Terminal
Emulation

The TN5250 T er minal Emulation User’ s Guide, explains ho w to configure and
use the TN5250 emulation on your terminal. This emulation is an option for
terminals.

This guide is organized into three chapters and two appendixes:

◆

Chapter 1, “Getting Started,” explains TN5250 terminal emulation
connection definitions, connections, and emulator sessions.

◆

Chapter 2, “The Menu System,” e x plains the TN525 0 onlin e menu sy stem
including keyboard mapping, and how to navigate through the menu
system.

◆

Chapter 3, “Terminal Keyboard,” compares TN5250 and terminal keys,
and outlines t he terminal’s keyboard feat ures.

◆

Appendix A, “Error Messages,” lists error messages and solutions to
problems reported by those error messages.

◆

Appendix B, “Troubleshooting Aids,” provides a short guide for
preparation in troubleshooting your terminal.

TN5250 terminal emulation provides the protocol to connect a terminal to
IBM midrange systems (AS/400 servers). Once connected, the user can access
and use legacy applications such as database and word processing through a
terminal.

Product Features

TN5250 terminal emulation includes these easy-to-use features:

◆

Interactive keyboard mapping

◆

TN5250-style screen attributes, including color and attribute settings

◆

Multiple sessions

◆

Telnet protocol

◆

Color terminal support

vi Overview

The TN5250
Connection

Guide Format
Conventions

To operate TN5250 emulation, you must connect to an AS/400 server
operating with OS/400 V ersion 1, release level 3.0 or higher . Additionally , you
must be operating the emulator across a TCP/IP network, using an IBM 8209
or equivalent TCP/IP attachment. When you use TN5250 terminal emulation,
you are communicating directly with the AS/400 server. This communication
is accomplished with the IBM AS/400 system internet protocol. Figure 1
shows the TN5250 connection related to a terminal.

Getting Started

This chapter discusses how to initiate TN5250 terminal emulation and
explains:

◆

Downloading the TN5250 terminal emulation option.

◆

Defining and using TN5250 connections.

◆

Opening and exiting sessio ns .

Read this chapter carefully before attempting to connect to a TN5250 server.

Downloading
TN5250 Option

TN5250 Server
Connection
Definitions

Preexisting
Connection
Definitions

The downloading of the TN5250 is similar to a flash download, and is done
through the serial port, the parallel port, the Remote Administratio n tool, or
the PCMCIA card.

❖

Note TN5250 terminal emulation can be downloaded only to some
terminals. Contact your system administrator or see the Terminal Firmware
Download Instructions for options available for your terminal.

When your terminal is first turned on, the Connections dialog box dis plays. In
this dialog box you will see the Connections list box. It is a list of preexisting
connections. You can use one of these preexisting connections to connect to
and start TN5250 emulation, or you can define a new TN5250 connection.

❖

Note See your terminal’s connectivity guide for more information about
connection definitions and the Connections dialog box.

To use a preexisting connection definition:
1 Click on an appropriate connection name in the Connections list box (see

Figure 1-1).

2 Click on the Connect command button.

1-2 Chapter 1

You will connect to the host you specified in the connection definition
selected. Connection definitions appearing in the Connections list can be
edited. To edit:

1 Select the connection that you want to edit from the Connections list.
2 Click on the Setup command button in the Connections dialog box.
3 Click on the Properties command button in Connection Setup dialog box.

The Connection Properties dialog box displays. Use this dialog box to edit
your preexisting connection de finition.

New Connection
Definitions

If the connection def initio n you w ant does no t already e xist in t he Connections
list, you can create one by:

1 Click on the Setup command button in th e Connections dialog box.
2 Click on the New command button in the Connection Setup dialog box.
3 Click on the Terminal Emulation radio button, then the OK command button

in the New Connection dialog box.

❖

Note See your terminal’s connectivity guide for more information about
instructions 1 throu gh 3 ab o ve. Refer to Figure 1-1, the Connection Properties
dialog box, while executing instructions 4 through 8.

6 Enter a server name and any command options (see Table 1-1, TN5250

Command Options), in the Server Name entry field.

❖

Note The port command option (for example 5250) should be included in
the server name entry.

❖

Note If the TN5250 terminal type is grayed out, check with your
Administrator to see if the TN5250 application firmware has been
downloaded to your terminal.

7 If you wish to activate the reverse video display, click the Reverse Screen

button. This effects reverse video in all the subsequent displays of the

session.Click on the OK command button.
8 Click on the Close command button in the Connection Setup dialog box.
After you click on the Close command button, a dial og box appears di splaying

the message:

Flash Write In Progress, Do Not Power Down Unit

This message indicates that your new connection definition is being stored in
the terminal’s memory.

When the flash write is finished, the new connection appears in the
Connections list in the Connections dialog box. To connect, highlight the
connection, then click on the Connect command button in the Connections
dialog box. A message displays:

Sessions

If you connect to a TN5250 server using a definition that contains an IP
address, the emulator will open up an initial TN5250 ses sio n (emulator­opened session) using that IP address. That session will be placed in the
Sessions list in the Sessions menu, as the initial open session (see Chapter 2,
“The Menu System,” for more information).

If you try to connect to a server using a definition that does not contain an IP
address, you will not connect. Instead, the emulator will display the TN5250
menu system, allowing you to create a session (user-opened session). Once a
session is created, you can then connect and run your session.

A session must be opened to use TN5250 terminal emulation. This section
discusses both emulator-opened sessions and user-opened sessions.

Getting Started 1-5

Emulator-Opened
Sessions

If you have specified an IP address in your connection definition, then once
connected the Pass Through Screen displays (see Figure 1-2).

If you have not specified an IP address in your connection definition, then
Main Menu - TN5250 displays (the main menu of the TN5250 user interface).
Use this menu to open your initial sessi on. You will need to open a session to
continue.
