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.
