Solution:

Verify the following:

Make sure that you specified the correct filename.

Verify that you did not assign a name to a device which is
already used by a file.

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.

.

ESTB—Serial poll status byte(s) lost

Cause:
