摘　　要：数据采集系统需要PC机与现场数据采集仪器进行控制、监测与数据交换,经常要对计算机的端口进行读写操作.这里主要研究了在BorlandC++Builder环境下如何嵌套汇编语言实现对端口的读写,从而实时获取数据,达到了很好的效果,并在相应的实例中进行了详细的探讨.It is necessary for the computer to control,supervise and communicate with the instruments in the data acquisrtion system.Crtainly communication with the port of the PC is frequent and neccessary too.This paper mailly introduced how to read and write the port of the PC and consequently obtained data real time with the program of C++ builder nested assemble language,discussed the method described above in the corresponding example at length.
