Displaying and Customizing Keyboard Maps

Displaying and Customizing Keyboard Maps

Introduction

Although the default TN3270 keyboard maps are sufficient for most users, some may want to customize keyboard maps for specific applications. This section describes the default keyboard maps and the options for displaying and customizing them.

There are two ways to manage customization of keyboard maps: on a server-wide basis and a port-by-port basis. Server-wide customization may be preferred because it addresses multiple users’ needs and makes more efficient use of the access server NVRAM. The server-wide customization must be set up by the privileged user, while port-by-port customization can be done by the port user.

Server-Wide Keyboard Maps Customization

Server-wide customization of keyboard maps depends upon the fact that each keyboard map is associated with a terminal type. The privileged user can create a new terminal type and associate a new keyboard map with it. Then he or she can customize the new map, which changes the key assignments that go with IBM 3270 functions.

A port user can then associate a port with the new terminal type. This automatically sets up the port to use the new keyboard map (see the following figure).

Default Server-Wide Terminal Types and Keyboard Maps

This section discusses the default server-wide keyboard maps and then explains how to define and customize new keyboard maps. The Selecting and Customizing Keyboard Maps for a Port section discusses keyboard maps for ports.

By default, the access server offers five different terminal types. Each terminal type is associated with one of two default keyboard maps, VT100 and VT220.

You can display the default terminal types and keyboard maps with the following command:

Local> SHOW TN3270 TERMINAL
