The Application of Control Technology Based on Serial Port Communication

In this article data glove and mechanical arm are connected by RS-232 serial port line, so mechanical arm and data glove are very critical in the data transmission among computers. Under windows serial port communication can be realized in the two methods below: making use of ActiveX control and API communication function. In this passage the advantages and shortcomings of the realization of the two methods will be compared, and the method which is the most suitable for this article will be chosen, and the mechanical arm control program will be developed.
