I am programing for control the oscilloscope(Tektronix DPO70604C) with GPIB-USB-HS.
My development environment is Visual Studio 2012 C# and use "NI-488.2 Language Interface(LangInt.dll)" for control GPIB-USB-HS.
The control is succeed at first and continue. But the error "ENOL : No Listener (2)" is come out from "ibwrt" function occasionally.
The software is communicating to oscilloscope until just before.
This "ibwrt" function is used many times in my software.
This problem can resolve by software restart.
This error occur from my customer's office. so I have not able to repro this error on my environment.
Why is this error coming?
Please tell me how to control without this error, or how to recover without software restart.
Thanks
