摘要
针对Windows环境下串行通信机制,研究了DOS环境下与之相对应的功能实现方法,提出了C语言程序设计方案。在系统通信中,设置数据流控制协议,开辟环形缓冲区处理通信数据,调用串行口的中断管理资源,实现异步通信,确保数据通信实时、稳定,效果良好。
Contraposing the serial communication mechanism of the windows system, of the corresponding realization method for DOS system is studied, and introduces programming precept based on C language is introduced. In system communication, in order to realize the asynchronous serial communication, it sets the command agreement of the data stream, assigns a cricoid buffer to manage the communication data, and uses the serial port's interrupt mechanism. This technique insures the data communicates steadily in real time, and brings into better effect.
