The device has two buffer areas, which are the serial data buffer and the network data buffer. When the SOCKET clear cache
function is enabled, only the cache data of the relevant SOCKET link will be cleared, and the serial cache data will not be cleared.
3.5.9 Link/ data transmission indication
Link indicates the status of the network connection. In TCP mode, when the network is not connected, the Link is off, and when
the connection is established, the Link is always on. The Link indicator is always on in UDP mode.
The other one is the data transmission indication, showing the transmission status of the DTU. When there is no data transmission
on the DTU, the data transmission indicator is off. When there is data transmission on the DTU, the flashing indicates that the period is
60ms and the indicator is on for 10ms.

The DTU is restored to the factory settings either by software or by button.
