The control-and-inquiry interface, which provides control and inquiry capability
to an application program. This interface (which is also provided by the SCP)
allows an application program to send commands to the subsystem to control the
subsystem or to obtain information.
The Event Management Service (EMS) interface, which provides event-
management capability to an application program. This interface allows an
application program to retrieve event messages previously sent to EMS by the
subsystem.
Figure 1-2 illustrates the architecture of the TELNET subsystem and the various
interfaces to the subsystem.

Both the programmatic and interactive management interfaces use SPI message
formats and conventions. To select the interfaces that will best serve your
management needs, examine and evaluate the features and capabilities of each
interface and the environment in which it will be used.
