Helpful Hint
Now that your software and hardware are installed and you have used some NI-
488.2 routines, read the NI-488.2 MS-DOS Software Reference Manual for a
description of all of the NI-488.2 routines available for the
GPIB-PCII/IIA. After reading about these functions and their capabilities,
practice using them with your programmable instrument or device in an
interactive environment using the IBIC program described in Chapter 6 of the
NI-488.2 MS-DOS Software Reference Manual.
