Error Code
If a GPIB-PC function completes with an error,
IBIC
also displays the
error mnemonic. The following example illustrates an error condition
occurred in the data transfer.
Example:
dev1:
[8100] (err cmpl)
ERROR: ENOL
COUNT: 1
dev1:
ibwrt "f2t3x"
In this example, there are no Listeners; perhaps
dev1
is powered off.
