A serial is being used to wait until an instrument is ready for data output before GPIB READ executes by reading Status byte. But occasionally, a serial poll queue overflow error occurs (error code 15). Does any one have any idea in general ?
How fast are you polling for bytes? What datya rate are you running at? Do you have a wait in the loop where you are waiting for data to come in? Remember that by computer standards, serial communications at its best is still very slow.
Finally, does the same thing happen when using any of the serial IO examples that ship with LV?
