How to change state of GPIB control lines when not CIC, problem with iblines

$

Hello,

 

I am writing code as the device/instrument as another system is the CIC. It is polling iblines to obtain the status, and my gpib device is reporting that NRFD is active. I cannot find a way to control these lines to be able to set the state of the control lines. I don't understand why GPIB is setting this line high when I first find the gpib adapter and setup device settings. Is there a function that will clear the control lines, when not CIC? ibclr and other functions error as my system is not the CIC.

 

Thanks

Phil
