Conﬁguring and Managing 3270

Terminal Emulation (TN3270)

Overview

Introduction

This chapter explains how to conﬁgure and manage the 3270 Terminal Emulator

(TN3270) software for the access server. This software enables ASCII terminals

and PCs to access IBM applications.

The TN3270 software enables an ASCII terminal to emulate an IBM 3278 Display

Station Model 2. The display screen of this model has 80 columns and 24 rows.

The TN3270 software performs the following tasks:

• Translates the ASCII terminal data stream into the 3270 data stream and

transmits it to the IBM host.

• Receives the 3270 data stream from the IBM host and translates it into the

ASCII terminal data stream.

The access server uses Telnet over TCP/IP to access applications on IBM hosts.

This chapter assumes a basic understanding of applications for IBM 3270

Information Display Systems and terminal emulation. This chapter also assumes

that the system manager at the host site conﬁgures the appropriate TCP/IP

software.
