This refers to the English sign that the event filtering in Serial Communication fails.

Serial communication

Serial communication refers to a communication mode that data is transmitted bit by bit between peripherals and computers through data signal lines, ground lines and control lines. This communication method uses fewer data lines, which can save communication costs in long-distance communication, but its transmission speed is lower than parallel transmission.

Application

With the application of computer system and the development of microcomputer network, the communication function is becoming more and more important. The communication here refers to the information exchange between computers and the outside world. Therefore, communication includes the information exchange between computers and external devices, as well as between computers. Because serial communication is a bit-by-bit transmission of information on a transmission line, there are few transmission lines used, and information can be transmitted by means of ready-made telephone networks. Therefore, it is especially suitable for long-distance transmission. It is also common to exchange data in serial mode for human-computer exchange equipment and serial storage external equipment, such as terminals, printers, logic analyzers, disks, etc. In real-time control and management, in a hierarchical distributed control system composed of multiple microcomputer processors, the communication between CPUs is generally in serial mode. Therefore, serial interface is a common interface for microcomputer application systems. Many peripherals and computers communicate in serial mode. The serial mode here refers to the information transmission mode between peripherals and interface circuits. In fact, CPU and interface still work in parallel mode.
