Error Handling General programming considerations for handling errors that occur when using
management-programming interfaces are discussed in the Communications
Management Programming Manual.
The programmatic control-and-inquiry interface to the TELNET subsystem features
two values for the return token; these values indicate that the response record does not
contain an error list. One value, ZSPI-ERR-OK, means that no error or warning
occurred. The other value, ZCOM-ERR-EMPT-RSP, indicates that there is no response
to be returned.
Error-handling considerations for specific commands are described in Section 6,
“Commands and Responses.”
Security Security for the TELNET subsystem is handled by SCP, as described in the
Communications Management Programming Manual.
Some commands are sensitive commands, meaning that they can be issued only by
certain users. When a user who is not allowed to issue sensitive commands attempts
to issue one, SCP returns an error. For more information on sensitive commands, refer
to “Sensitive and Nonsensitive Commands” in Section 6, “Commands and
Responses.”
