Regardless of what the manual says, I have seen defect reports that indicate
that the SRQ behaviour of the 2225A is not reliable.  The problem seems to
be unique to the 2225A.  Reported defects include:
  - Only the first SRQ after power-up is detected.
  - Spurious SRQs are detected, and when SPOLL'd, the 2225A denies having
    any reason for the SRQ.
