Chapter 7 Interactive Control Utility
NI-488.2 User Manual 7-12 ni.com
Count Information
When an I/O function completes, the Interactive Control utility displays the
actual number of bytes sent or received, regardless of the existence of an
error condition.
If one of the addresses in an address list to a multi-device NI-488.2 call is
invalid, then the error is EARG and the Interactive Control utility displays
the index of the invalid address as the count.
The count has a different meaning depending on which NI-488.2 call is
made. For the correct interpretation of the count return, refer to the function
descriptions in the NI-488.2 online help. For instructions on accessing the
online help, refer to the Using the NI-488.2 Documentation section in
About This Manual.
