IBM Host Communications

IBM Host Communications

Introduction

This section describes IBM host communications with a terminal attached to the access server.

Connecting to an IBM Host

After you complete the basic configuration of a port for 3270 emulation, you can use the CONNECT, OPEN, or TELNET commands to access an IBM host. The following example shows a connection to an IBM host that uses the host’s Internet address:

Local> CONNECT 195.20.0.15

When the access server connects, follow the prompts that appear on the screen to log onto the host system.

To display the keyboard map defined for a session, enter the 3270 HELP function.

Entering and Editing Data

TN3270 supports the following data entry and editing features:

∙Unformatted and formatted screens

∙Normal and insert modes

For information about IBM 3270 data entry and editing, refer to the documentation provided with your IBM application.

Status Line Indicator

The status line indicator is a reverse video strip that displays messages on the bottom line of the terminal screen during a 3270 session. This indicator emulates the status line that appears on the bottom line of an IBM 3270 Display Station.

To turn the status line indicator on and off, enter the 3270 STATUS function.

The status line is overwritten when:

∙The IBM application moves the cursor to the last line on the screen.

∙You enter data on the last line of the screen.
