Abstract: A communication system with serial ports for automatically identifying device types and communication protocols and method thereof are described. The communication system and method are capable of automatically identifying the device types and communication protocols of interface devices with different serial device numbers which are disposed in the serial port architecture. Furthermore, the drivers are capable of performing a serial communication based on the serial port architecture for matching the device types and communication protocols correspondingly, thereby reducing the development and manufacturing costs of communication system. Moreover, the user of an application program module only needs to provide the device numbers and data control information without the cooperation of hardware circuits and manufacturing technique of the interface devices to complete the automatic control and monitoring tasks of the interface devices to increase the utilization convenience.

Abstract: An AC power supply socket is adapted for receiving an electrical plug and includes a housing having a top opening, a pair of socket terminals disposed in the housing, and a flexible cover mounted on the housing to cover the top opening sealingly. The cover has an insulating plate disposed above the socket terminals, and a pair of conductive hollow legs connected integrally with the insulating plate, aligned with the socket terminals, and adapted to receive a pair of conductive prongs of the plug. The insulating plate has an intermediate portion and two opposite flexible portions. The hollow legs extend downward from the intermediate portion into the housing without contacting the socket terminals in a normal state, and are movable downward further to contact the socket terminals when the insulating plate is flexed downward upon insertion of the plug into the hollow legs.
