3.2.11. Emptying Serial Buffer when TCP connection is established
Figure 3.13 Com Port: Enabling Serial Buffer
Type 3 from “Input choice and enter (1~4):” of COM1, by default COM port serial buffer is enabled meaning that
once a TCP connection is established, old serial data received from serial device before the connection will be
emptied. If this option is disabled, SE5001A will keep old serial data when the connection is broken (Figure 3.13).
