END S
8192
The END bit specifies whether the END or EOS message
has been received. The END bit is set in the status word
following a
rd
function if the END or EOS message was
detected during the read. While the GPIB-232CT is
performing a shadow handshake as a result of the
gts
function, any other function call can return a status word
with the END bit set if the END or EOS message
occurred before or during that call. The END bit is
cleared in the status word at the start of any subsequent
programming message.
SRQI S
4096
The SRQI bit specifies whether a device is requesting
service. This bit is set in the status word whenever the
SRQ line is asserted. The bit is cleared whenever the
GPIB SRQ line is unasserted.
CMPL S/G
256
The CMPL bit specifies that the operation relating to this
status information is complete. This bit is always set, and
is useful in identifying the status word from other
responses.
LOK S
128
The LOK bit specifies whether the GPIB-232CT is in a
lockout state. The LOK bit is set whenever the
GPIB-232CT detects the Local Lockout (LLO) message
has been sent either by the GPIB-232CT or by another
Controller. The LOK bit is cleared when the Remote
Enable (REN) GPIB line becomes unasserted either by
the GPIB-232CT or by another Controller.
