EOIP (10)
EOIP occurs when an asynchronous I/O operation has not finished before
some other call is made. During asynchronous I/O, you can only use
ibstop, ibnotify, ibwait, and ibonl or perform other non-GPIB
operations. If any other call is attempted, EOIP is returned.
Solutions
Resynchronize the driver and the application before making any further
NI-488.2 calls. Resynchronization is accomplished by using one of the
following functions:
ECAP (11)
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.
Solutions
Check the validity of the call, or make sure your GPIB interface and the
driver both have the needed capability.
ibnotify callback If the ibsta value passed to the ibnotify
callback contains CMPL, the driver and
application are resynchronized.
ibnotify If the returned ibsta contains CMPL, the
driver and application are resynchronized.
ibwait If the returned ibsta contains CMPL, the
driver and application are resynchronized.
ibstop The I/O is canceled; the driver and application
are resynchronized.
ibonl The I/O is canceled and the interface is reset;
the driver and application are resynchronized.
