Aiming at the shortcomings of the current serial port to network port data transmission module,such as slow trans-mission speed,poor stability,remote configuration of serial port parameters,a high-speed serial port to Ethernet server based on CH579 single chip microcomputer was proposed.The serial port server improved the data transmission rate by adopting the eight-level FIFO cache of the serial port.By optimizing the frame mechanism of the serial port,the system stability was improved.The remote configuration of serial port parameters of the host computer can be realized by designing the serial port parameter configu-ration protocol.The test results show that the system can realize the transparent transmission of data from serial port to network port,the highest baud rate can reach 5Mbit/s,and the average packet loss rate is 0.065 0％.The system has obvious improve-ment in the improvement of serial port baud rate,stability and universality.
