Definitions specific to the TELNET subsystem are described here.
ZSPI-SSN-ZTNT
specifies the subsystem number assigned to the TELNET subsystem. This value
name is defined as a constant in the SPI DDL file, ZSPIDEF.ZSPIDDL.
ZSPI-TKN-ALLOW-TYPE
indicates, within a command buffer, the conditions under which the processing of
a set of objects will continue. This token applies to only those commands that
accept object-name templates. The ALLOW-TYPE token controls whether the
subsystem continues to the next object of a set when an error or warning appears
during the processing of an object; it does not control the response when the
tokens within a command message are incorrect or missing. The TELNET
subsystem supports only the following value for this token:
ZSPI-VAL-NORM-ONLY
indicates that the TELNET subsystem continues to process the next object in
the set if the command completed successfully on the previous object. The
response buffer cannot contain an error list. This is the only supported value.
ZSPI-TKN-CHECKSUM
provides checksum protection against the accidental corruption of the SPI buffer
between calls to the SPI procedures. Here are possible values for this definition:
ZSPI-VAL-FALSE
indicates no checksum protection.
ZSPI-VAL-TRUE
indicates checksum protection.
ZSPI-TKN-COMMAND
specifies the command number of a TELNET command. The value of this token is
always ZCOM-CMD-name, where name specifies the command to be performed.
The commands supported by the TELNET subsystem are described in Section 6,
“Commands and Responses.”
ZSPI-TKN-COMMENT
allows the requester to include comment information, which is not acted upon by
the server or returned by the server. The requester can include as many as 80
bytes of comment in every command. If the comment exceeds this number of
bytes and causes a command to be too large for the server’s read buffer, the server
is not responsible for recovery. The TELNET subsystem guarantees only 80 bytes.
