EFSO—File system error
Cause: A problem was encountered while performing a file operation.
Solution: Verify the following:
• Make sure that you specified the correct filename.
• Check the spelling and the path.
• If you need more room on the disk, delete some files.
• Verify that you did not assign a name to a device which is
already used by a file.
EBUS—Command byte transfer error
Cause: A GPIB bus error occurs during a device function.
Solution: • Determine which device, if any, is abnormally slow to
accept commands and fix the problem with the device.
• Lengthen the assigned time limit using ibtmo or
ibconfig .
ESTB—Serial poll status byte(s) lost
Cause: One or more serial poll status bytes received during an automatic
serial poll was lost.
Solution: Call ibrsp more frequently to read the status bytes. Ignore the
ESTB error.
Note: This error occurs only during ibrsp functions.
