Autopolling and Interrupts

If autopolling and interrupts are both enabled, the NI-488.2 software can perform autopolling after any device-level NI-488.2 call provided that no GPIB I/O is currently in progress. In this case, an automatic serial poll can occur even when your application is not making any calls to the NI-488.2 software. Autopolling can also occur when a device-level ibwait for RQS is in progress. Autopolling is not allowed when an application calls board-level traditional or multi-device NI-488.2 calls, or the stuck SRQ (ESRQ) condition occurs.
