数据采集系统上位机设计。包括串口通信、文本显示、曲线实时显示、数据保存、监测报警等功能。-data acquisition system software design. Including serial communication, text, real-time curve display, data preservation, alarm monitoring, and other functions.

个人原创，已经测试通过。功能：完成串行数据与RS232格式数据的收发转换，ST16C450+串并双向转换兼收发时序产生功能，优点：省去了传统的ST16C450需要CPU干预的缺点，简化设计， 纯硬件自动转换，缺点：忽略各种异常报警，适用于误码测试时使用（传输错误由误码测试功能模块完成检测）。,Personal originality, have the test. Function: the completion of serial data and send and receive RS23
