The Serial is a common communication mode.In order to access and communicate with the net easily and quickly through the serial,this paper introduces the technology of the UMDF driver mode,the TCP/IP working mode,the serial communication programming and the Socket communication programming etc.It also introduces the method of creating serial driver,along with the working principle and designing process of the three working mode,which base on serial port to net port communication.In the end,it gives the test to the serial communication.Because of the realization with programming,it doesn’t need refitting the equipment or adding new equipment,so it greatly simplifies the work and reduces the cost of hardware.
