Getting Help with I/O Configurator Commands
The help facility enables you to identify quickly the function and syntax of those I/O configurator commands
and options required to perform the multiple operations that define or change device-dependent information.
To see a list of the commands available for use in the I/O configurator and their abbreviations, enter HELP at
the I/O configurator prompt. To display the syntax for each available command at the current level, enter
HELP ALL, as shown in Example 5-2.
