in status is set or cleared can be found in Appendix B.
The GPIB-232CT updates
status
and
count
at the end of
each programming message. It updates
GPIB-error
and
serial-error
whenever a new error occurs.
GPIB-
error
and
serial-error
are cleared only after you have
requested status.
Refer to the following examples for ways in which to use the
status information.
When you wish to begin continuous status reporting, send the
stat c s
,
stat c n
, or
stat c n s
programming
message. When you call
stat
with both
n
and
s
modes
specified, the numeric status is always returned first.
If you call
stat
without an argument, continuous status
reporting is disabled.
