All values except "BUSY" are final results. In case "NO_ERROR" is returned, the requested action has been successfully performed. "NO_ERROR_NO_DATA" also indicates a successful completion. The only difference to "NO_ERROR" is the fact, that there is one (more) data to be provided. All other return values (except "BUSY") are final error states. In case a method or function returns "BUSY", it has to be called again in the following cycles until it returns a final result.
