@item @b{init} This command terminates the configuration stage and enters the normal
command mode. This can be useful to add commands to the startup scripts and commands
-such as resetting the target, programming flash, etc.
+such as resetting the target, programming flash, etc. To reset the CPU upon startup,
+add "init" and "reset" at the end of the config script or at the end of the
+openocd command line using the -c option.
@cindex init
@item @b{telnet_port} <@var{number}>
@cindex telnet_port
@item @b{daemon_startup} <@var{mode}>
@cindex daemon_startup
@option{mode} can either @option{attach} or @option{reset}
-Tells the OpenOCD whether it should reset the target when the daemon is launched, or
-if it should just attach to the target.
+This is equivalent to adding "init" and "reset" to the end of the config script.
+
+It is availble as a command mainly for backwards compatibility.
