| 2 | empty | 0 | Initial status | |
| "4,end.#MSG1,12.5," | 2 | "4,end.#MSG1,12.5," | 0 | A not complete message with a previous not complete message is arrived |
| "end.#MSG1,23.5,end." | 2 | "4,end.#MSG1,12.5,end. #MSG1,23.5,end." | 0 | The rest of the message is arrived with a new complete msg. The block identifies the first msg head in the buffer and the first following message end. |
| "" | 0 | "#MSG1,23.5,end." | 1 | the block outputs data. The control pass to the next block. The first message, with the part of the incomplete message, is removed from the internal buffer. |
| "" | 1 | empty | 1 | the block outputs data. The control pass to the next block |
