RQS OFF inhibits all SRQ's (except power-on event) so
in this mode the ERR? query allows the controller to find out
about events without first performing a Serial Poll. With
RQS OFF, the controller may send the ERR? query at any
time and the instrument returns an event waiting to be re-
ported (see Table 2-4). The controller can clear all events by
sending the error query until a zero (0) code is returned, or
clear all events except power-on through the DCL interface
message.

With RQS OFF the controller may perform a Serial Poll,
but the Status Byte only contains Device Dependent Status
information. With RQS ON, the STB contains the class of
the event and a subsequent error query returns additional
information about the previous event reported in the STB.
