The help command displays information about the available RedBoot commands. If a topic is given, then the display is restricted to information about that specific command.
If the command has sub-commands, e.g. fis, then the topic specific display will print additional information about the available sub-commands. special (ICMP) packets to a specific host. These packets should be automatically returned by that host. The command will indicate how many of these round-trips were successfully completed.
Show generic help. Note that the contents of this display will depend on the various configuration options for RedBoot when it was built.
