TCP/IP TELNET Management Programming Manual

Preface
53474 Tandem Computers Incorporated ix
This manual describes the subsystem-specific information needed by an application
programmer to develop an application that manages the Tandem TCP/IP TELNET
subsystem according to the Distributed Systems Management (DSM) procedures. It
includes detailed descriptions of the TELNET subsystem control-and-inquiry interface
and the TELNET subsystem Event Management Service (EMS) interface. Essentially,
this manual defines the specific commands, responses, objects, messages, and tokens
supported by the DSM programmatic interface to the TELNET subsystem.
This manual is intended for application programmers in the following categories:
TAL and C programmers writing management applications that communicate
with the TELNET subsystem.
COBOL85 programmers using ENTER TAL and writing management applications
that communicate with the TELNET subsystem.
TACL users writing macros and routines to perform management functions on the
TELNET subsystem.
In this manual, all references to the TELNET or TCP/IP subsystem, process, or
commands, refer specifically to the Tandem TCP/IP or Tandem TCP/IP TELNET
product.
The seven sections and two appendixes of this manual contain the following
information:
Section 1 introduces the TELNET subsystem and the objects controlled by the
subsystem. It also describes the required management functions, the relationship
of the subsystem to other subsystems, and the architecture of the TELNET
subsystem.
Section 2 describes the management programming for the TELNET subsystem.
This section describes the purpose of management programming and how
applications fit into the DSM architecture. It also contains tables of TELNET
programmatic commands and a comparison of programmatic and operator
commands.
Section 3 describes the elements of Subsystem Programmatic Interface (SPI)
messages. It includes discussions of definition files, naming guidelines, and the
various types of tokens that make up commands, responses, and event messages.
Section 4 describes SPI programming considerations for the TELNET subsystem.
This description includes information about building the command buffer,
canceling commands, receiving and decoding response buffers, error handling,
version compatibility, and security.
Section 5 summarizes standard SPI standard definitions, EMS standard
definitions, and data communications standard definitions used by the TELNET
subsystem in multiple commands, responses, or event messages. These definitions
include token codes, token maps, token types, token values, field types, and field
values.
