*CLS
Description This command sets the contents of the Standard Event Register
(ESR), the Status Byte Register (STB), and the Error Queue
(ERR) to zero. This command is commonly used to clear the
status registers before enabling SRQ. Note that the output
queue, Standard Event Status Enable Register (ESE), and
Service Request Enable Register (SRE) are not affected.

register. A non-zero result will set the Event Summary Bit (ESB)
of the Status Byte Register (STB). This command is useful for
selecting which events may generate an SRQ.
