    IO error

    Hi,
    I am trying to get the data out of an instrument through its GPIB port
    and using python code. I am able to perfectly control the operation of
    the instrument with my code. But I have not figured out a way as yet
    to get the data of the GPIB.
    I thin that it will go through 2 steps:
    1) instrument transfers data to its output buffer
    2) Read from the output buffer.

    When i try read() command it gives me an IO timeout error.

    Any suggestions?

    Thanx in advance.

      What's the device name, device driver module name, do you have any sample or
      diagnostic code you can run to prove that your PC is communicating properly
      with the device?

          Hi..
          I am trying to automate an HP 4156. I am getting some of the data that
          i need, but when i specify the whole data set i want it to read, it
          takes some time and gives a IO Timeout error.
          Will making IO timeout=0 help?

              What's the device name as far as the OS is concerned that you are specifying
              to open the device, device driver module name, do you have any sample or
              diagnostic code you can run to prove that your PC is communicating properly
              with the device?
