Hi,
Autopolling is handled by the ENET's firmware. You use ibconfig IbcAUTOPOLL to enable or disable autopolling.
You can check the status variable (ibsta). Bit 12 is SRQI and will be set when an SRQ occurs. Even if autopolling is enabled, the SRQI bit will remain set until ibrsp is executed.
Hope this helps.
