ECAP results when your GPIB interface lacks the ability to carry out an 
operation or when a particular capability has been disabled in the software 
and a call is made that requires the capability.

Check the validity of the call, or make sure your GPIB interface and the 
driver both have the needed capability.

EFSO results when an 

ibrdf

 or 

ibwrtf

 call encounters a problem 

performing a file operation. Specifically, this error indicates that the 
function is unable to open, create, seek, write, or close the file being 
accessed. The specific operating system error code for this condition 
is contained in 

ibcntl

.

Possible solutions for this error are as follows:

•

Make sure the filename, path, and drive that you specified are correct.

•

Make sure that the access mode of the file is correct.

•

Make sure there is enough room on the disk to hold the file.
