Abstract

This graduation design is developed with VC++ in Windows system, the main content is file transfer system based on Serial port. In the design process, we made the following aspects: First, to present the prospects for Serial port communications applications, a summation of the engineering significance; Secondly, to present the Win32 API function and MSComm controls; Again, to present the practical and the worth of scheme, and Serial port communications features in the application and development skills in specific areas to be describe; Finally, to give the code of current design for the reader reference.

Serial port communication have broad applications in various fields .We can understand the basic principles of Serial port communication in engineering applications and communications products ,and master the development tools VC++ through this design.

Keywords: Win32 API,File Transfer, Serial port communications, MSComm, VC++
