Count Return in Interactive Control
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 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 help for that function, which you can access through the Index of this help file.
