Seems NI-communicator controller is not performing the Serial Polling.

Hi,

I am writing a Gpib Device driver. In that I am facing some issues mentioned below:-

1. It seems NI-communicator controller is not performing the Serial Polling. It detects the RQS and enable the same on communicator panel But it does not update SRQI bit on NI-communicator penal.

Do I also have to handle the serial polling at device side if yes then how can I detect that communicator is requesting for serial polling?

 

I have wrote my own controller using VISA API and found that all bits which I have set at device side are reflecting properly. I am afraid why it is not getting update in NI-communicator.

 

2. Once RQS is set NI-Max does not reset the same. If I close the NI-communicator panel and reopen the same it goes.

 

Please let me know if I am misstaken some where in NI-Communicator settings?

 

Thanks
