Visual Basic与RS-232串行通信控制。 应用Visual Basis中的串行通信控件MSComm,通过实例循序渐进地介绍了自动化的基础—Rs232串行通信.从简单的串行通信概念、实验到复杂的仪器控制，本书都提供了完整的Visual Basic范例、将应用扩展到硬件控制，同时还介绍了Visual Basic 6.0自身具有的串行通信控件，串行通信控件的细节，控制调制解调器并进行文件传输，用串行通信端口来控制仪器，将串行通信扩展到分布式监控等内容。-Visual Basic and RS-232 serial communication control. Applied Visual Basis of serial communication control MSComm, through examples step by step introduction to automated basis-Rs232 serial communication from simple serial communication concepts, experiments to complex instrument control, this book provides a complete Visual Basic example, the applications to the hardware control, and also introduced its Visual Basic 6.0 with serial communication control, the details of serial communication control, file transfer and modem control, serial communication port to control the instrument, the serial extended to distributed monitoring communication content.
