Query Errors
These are error messages in the range -400 to -499. They indicate that an error
has been detected by the output queue control.
A device-specic error is signaled by the query error bit (bit 2) in the event
status register.
-300 Query error. This indicates that a query error has occurred. No more
specic information is available.
-410 Query INTERRUPTED. A condition occurred that interrupted the
transmission of the response to a query (for example, a query followed by a
DAB or a GET before the response was completely sent).
-420 Query UNTERMINATED. A condition occurred that interrupted the
reception of a query (for example, the instrument was addressed to talk and an
incomplete program message was received).
-430 Query DEADLOCKED. A condition causing a deadlocked query has
occurred (for example, both the input and the output buer are full and the
device cannot continue).
-440 Query UNTERMINATED after indenite response. Two queries were
received in the same message. The error occurs on the second query if the rst
requests an indenite response, and was already executed.
