CHAPTER 2
OPERATION AND APPLICATION
2.1 INTRODUCTION
This chapter provides an introduction to the UNILINK Host Adapter operation
and how it can be used in typical applications. You should refer to Chapter 5 for
the complete command syntax and to the Glossary for help with any unfamiliar
terms. Network planning forms are located in Appendix E, Appendix F, and
Appendix G.
2.2 COMMAND PROCESSING
The UNILINK Host Adapter commands are a set of functional tools to help you
direct network applications. Each command consists of a one-byte command
code and one or more parameters as shown in Figure 2–1. Most parameters
have default values that were selected to help you quickly install an operational
network and expand it with minimal software changes. As your network grows,
you can improve network efficiency by redefining the parameters to match your
network needs. Figure 2–2 illustrates the relative performance and flexibility
gained with using additional commands.
