RS422串口编程

上传个考勤系统,希望别人也能用.该代码只能算初级的东东,软件代码复用性不高,重复代码比较多.唯一感觉有点取鉴的可能就是端口和dll的连接,还有线程的使用,本想改一改,但是手头没有考勤机了,对应考勤机是890C的.-From a performance appraisal system, I hope others can use. The code can only count the primary Dongdong, software, code reusability is not high, repeat the code more. The only feeling a little check Kam is probably dll ports and connections, There are threads to use, simply wanted to, but do not have attendance machine, and the corresponding attendance machine is the 890C.

微机实现异步通信是依靠适配器来完成的，而后者又是以UART芯片，即通用异步收发器芯片为核心构成的。 IBM PC的异步通信适配器使用的UART芯片为INS 8250。 -Computer realize asynchronous communication relies on the adapter to be completed, which in turn is a UART chip, which UART chip at the core composition. IBM PC

项目描述: slsnif is a serial port logging utility. It listens to the specified serial port and logs all data going through this port in both directions. Serial line sniffer是一个串行端口记录工具。它监听指定的串行端口并记录所有通过这个端口的两个方向的数据。 来源：http://freshmeat.net slsnif是一个串行端口日志工具。它监听特殊的串口，记录所有通过这具串口的两个方向的数据。 类别: Development Status: 5 - Production/StableEnvironment: Console (Text Based)Intended Audience: DevelopersLicense: GNU General Public License (GPL)Operating System: LinuxProgramming Language: CTopic: Communications, Debuggers -Project Description : slsnif is a serial port logging utility.
