Agilent- defined API for instrument I/O. Agilent SICL is
one of the IO Libraries installed with Agilent IO Libraries

A side- by- side installation allows two vendors'
implementations of VISA to be used on the same
computer. See also primary VISA and secondary VISA.
SRQ
An IEEE- 488 Service Request. This is an asynchronous
request (an interrupt) from a remote device that requires
service. In GPIB, an SRQ is implemented by asserting the
SRQ line on the GPIB. In VXI, an SRQ is implemented by
sending the Request for Service True event (REQT).
Standby Controller
A device or interface that has Controller capability, but is
not currently the Active Controller.
status byte
A byte of information returned from a remote device that
shows the current state and status of the device. If the
device follows IEEE- 488 (GPIB) conventions, bit 6 of the
status byte indicates whether the device is currently
requesting service.
symbolic name
A name corresponding to a single interface. This name
uniquely identifies the interface on this Controller or
gateway. When there is more than one interface on the
Controller or gateway, each interface must have a unique
symbolic name.
