SerialPollFlags - what does the value "4" mean ?

[Laro88]

Device.SerialPollFlags returns the value 4.... I don't see this value in the Enum SerialPollFlags.....

short spf = device.SerialPoll();

device is working fine - "*IDN?" responds as expected.

Are you using NI-488.2 and GPIB communication?

The SerialPollFlags does only have three types of enumerations: MessageAvailable(16), EventStatusRegister(32), and RequestingService(64).

The value of 4 could have several meanings, depending on what context it came in.

If it is possible, I would like to see a NI-SPY capture, screen shot of the error and the code.

This should help us get started with debugging the application. I would also like to see what version of the driver and operating system you are using.

Can you provide further information on your setup?
