摘　　要：介绍了一种在虚拟仪器中实现计算机串口与并口控制的方法。首先分析了并口与串口的结构特点,针对二者的不同,给出了控制程序,并对串口和并口在实际使用中的效果进行了分析。表明并口适用于状态信息的传递,而串口则使用数据的传递。A way to control serial port and parallel port in LabVIEW is introduced in this paper. The structure of serial port and parallel port is analyzed first, then the control programs are given according to the difference between serial and parallel port. The use of parallel and serial port are diferrent：the former is suitable for status information and the latter for data delivery.
