and name identifies the token type. For example, ZTNT-TYP- TRACE defines the
token type of the process object options for the TRACE command as enumerated
values.
See Section 5, “Common Definitions,” for all the token types used by the TELNET
subsystem.
Predefined Value Names
The predefined value names used by the TELNET subsystem are represented by
symbolic names having the form Zsss-VAL-name, where sss is a three-character
subsystem abbreviation and name identifies the predefined value. For example, the
predefined value ZTNT-VAL-SSID represents the subsystem ID of the TELNET
subsystem present in all commands and responses associated with the TELNET
subsystem. See Section 5, “Common Definitions,” for all the predefined value names
used by the TELNET subsystem.
Field Types
The field types used by the TELNET subsystem are represented by symbolic names
having the form Zsss-DDL-ftype, where sss is a three-character subsystem abbreviation
and ftype identifies the field type. For example, the field type ZSPI-DDL-BOOLEAN
represents the Boolean data type. Although most field types are defined by SPI,
private field types can be defined by a subsystem. The TELNET subsystem, however,
does not define any private field types. Refer to Section 5, “Common Definitions,” for
all the field types used by the TELNET subsystem.
Constructs Involving
Multiple Tokens
The TELNET subsystem supports two kinds of constructs that involve multiple tokens:
data lists and error lists. For the TELNET subsystem, these constructs are found only
in a response buffer from the subsystem. A data list begins with the token ZSPI-TKN-
DATALIST, while an error list begins with the token ZSPI-TKN-ERRLIST; both end
with the token ZSPI-TKN-ENDLIST.
A data list is used in a response buffer to enclose information about one object or, in
some cases, a related group of objects.
An error list is used in a response buffer to enclose information about an error or
warning.
For further details on these two constructs, refer to the Distributed Systems Management
(DSM) Programming Manual.
Components of a
Command, Response, or
Event Message
For general information about the components of a command, response, or event
message, refer to the Communications Management Programming Manual.
For information on the tokens associated with each TELNET command, response, and
event message, see Section 6, “Commands and Responses,” and Section 7, “Event
Management.” For information on considerations for building and retrieving SPI
buffers, see Section 4, “SPI Programming Considerations.”
