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,
Utility.
