+ * privilege level of Callback and cannot be changed. All other sessions are
+ * initially set to USER level, regardless of the maximum privilege level
+ * requested in the RAKP Message 1.
+ *
+ * This command cannot be used to set a privilege level higher than the lowest

+ * the privilege limit for the channel that was set via the Set Channel Access
+ * command.
