ZCOM Error Codes
Meanings of the Error Codes
Chapter 2 23
ZEZLU (-7): ZLU is out of range
Explanation: An invalid ZLU was specified. The ZLU number must
be in the range from 1 to the total number of ZLUs
(Terminal-ZLU and Program-ZLU parameters) defined
in the TTGEN configuration file.
Action: Correct the application source code or increase the
Terminal-ZLU and/or Program-ZLU parameters in
your TTGEN configuration as needed.
ZEZCS (-8): ZLU checksum does not match
Explanation: The checksum for the specified ZLU does not match the
one stored in the ZCOM subsystem. This usually
indicates that the ZCOM subsystem has been
shutdown and then restarted (causing the checksum to
be recalculated) without the program’s knowledge. This
could also be caused by the application using the
incorrect checksum value for the supplied ZLU.
Action: Correct the application source code or restart the
application as appropriate.
ZEMODE (-9): Illegal request/control mode
Explanation: The ZCOM routine was called using an illegal mode or
request code parameter. For example, calling zsend()
with a mode value greater than 8 or less than 0.
Action: Correct the application source code.
ZEIFTNO (-10): Bad interface number specified
Explanation: An invalid Mux interface number was specified. This
number must range from 0 to the maximum Mux
interface number defined in your TTGEN configuration
file.
Action: Correct the application source code or your TTGEN
configuration file.
