Traditional solutions usually rely on manual intervention to re - establish the connection, which is not only time - consuming and laborious but also may lead to data loss and service interruption. Therefore, a method capable of automatically detecting and re - establishing serial port communication is needed to improve the reliability and stability of the system. Summary of the Invention
