Although all data communications subsystems must use symbolic names that have the
form ZCOM-CMD-name, each subsystem defines which commands it supports. The
TELNET subsystem supports the following commands:
ABORT LISTOPENS
ADD RESETSTATS
ALTER START
DELETE STATISTICS
GETVERSION STATUS
INFO STOP
LISTOBJECTS TRACE
These commands are described in Section 6, “Commands and Responses.”
Object Types Object-type numbers represent the object type (or class) of an object. The value of an
object-type number is subsystem-specific and also has a symbolic name. The symbolic
name has the form ZCOM-OBJ-type, where type identifies the object type. For
example, ZCOM-OBJ-WINDOW identifies the window object type in all data
communications subsystems, including the TELNET subsystem.
Note that object-type numbers are part of the header of each command and response.
The header token ZSPI-TKN-OBJECT-TYPE contains the object-type number.
However, if a response contains multiple objects or an object is returned within a data
list, the object-type number is contained in the ZCOM-TKN-OBJTYPE token. The
symbolic name of the ZCOM-TKN-OBJTYPE value also has the form ZCOM-OBJ-type,
where type identifies the object type.
The TELNET subsystem supports the following object types:
NULL
PROC
WINDOW
The objects defined for the TELNET subsystem are organized in a hierarchy by object
type. The WINDOW object type is subordinate to the PROC object type. The NULL
object type is not within the hierarchy and applies to only two commands,
GETVERSION and LISTOBJECTS. The hierarchy is important when issuing
commands to the TELNET subsystem for processing. For example, because the
WINDOW object type is subordinate to the PROC object type, any commands
pertaining to a WINDOW object can be issued only when the PROC object is in the
STARTED summary state.
Object Names An object name identifies a specific object. The object specified by an object name for
the TELNET subsystem must be either the PROC or WINDOW object type. The NULL
object type does not have an object name associated with it.
