(TRACE File Command)
This command interfaces with all modules to create an efficient TRACE File.
It is a monitor that stores and keeps track of information about events. For all
error conditions, a clear log of all actions is available. The TRACE File does
not solve these errors; it only indicates that there were errors and shows where
they originated. The TRACE File asks each module to report all events and
records the errors in order in a complete event log. Each event is marked with
a severity indicator.
LOG File
All hardware alarms, normal log messages, and severe events are logged in
one single LOG file.
ITG shell command set
ITG shell commands are designed to supplement overlay commands, and to

commands, connect a MAT PC or a TTY to the RS-232 Maintenance port on
the ITG card faceplate. Alternatively, connect the MAT PC or a TTY to the
Serial I/O Panel port to create a more permanent connection to the ITG card
maintenance port.
