Before you write your NI-488.2 application, you might want to use the 
Interactive Control utility to communicate with your instruments 
interactively by typing individual commands rather than issuing them from 
an application. You can also use the Interactive Control utility to learn to 
communicate with your instruments using the NI-488.2 API. For specific 
device communication instructions, refer to the documentation that came 
with your instrument. For information about using the Interactive Control 
utility and detailed examples, refer to Chapter 6,
