message in the Standard Event Status Register (SESR) when all pending

Output Queue when all pending operations are finished. The *OPC? response is
not available to read until all pending operations finish. For a complete
discussion of the use of these registers and the output queue, see page 3–35.

The command returns a single " " if the VXOA41 is in standard configuration

string of three fields, with each field separated by a comma. Each of the fields
represents one of the possible options. Since the options are mutually exclusive,
two of the fields will always be "0". One of the fields, which one depends on
what option is installed, will indicate the installed option with the syntax:
