This paper introduces a dynamic link library DLL created by VC + +, which is used to program the shortwave MODEM software which is used to transmit and receive half-duplex shortwave radio. The method of shortwave MODEM and computer serial port communication is analyzed, and several key points in communication programming are elaborated technology. Experimental results show that: the preparation of shortwave MODEM communication procedures to achieve the actual channel data on the pass, to solve the shortwave number of several problems. This shows that based on dynamic link DLL DLL MODEM communication programming method is effective
