Introduction
1-2 VT220/ANSI Terminal Emulation Programmer’s Reference Guide
Purpose of This Guide
The purpose of this programmer’s guide is to describe wire-
less terminal emulation stations and how they emulate
VT220 terminal operation. This guide describes:
"
How the wireless stations’ keyboards and overlays
emulate VT220 terminal operation.
"
Received codes and transmitted keyboard codes that
the wireless stations support.
"
Extended commands for the wireless stations.
"
Wireless station support for VT330 and VT340 ap-
plications.
Intended Audience
This programmer’s guide was prepared with the assump-
tion that you are already familiar with the operation of the
VT220 terminal. The intended audience is the host comput-
er programmer who is familiar with the VT220/ANSI data
stream, and needs to design interfaces to the wireless sta-
tions.
What to Read First
Before you begin using the wireless station as an emulation
product, read the section about the wireless station you are
using. The information will give you a basic understanding
of the equipment you will be working with. You can also
skim the appropriate program commands for programming
guidance on the VT220/ANSI commands the wireless sta-
tion supports.
