串口通讯中crc码计算方法，通过labview程序从而实现的。-err

本程序是win32api串口编程tty(虚拟终端)实例包括硬件控制的设置,因此可以用于对modem的编程-win32api Serial Programming tty (virtual terminals) Examples include control of the hardware installed, the modem can be used for programming

串口通信；串口调试助手的源代码，龚建伟老师的亲手笔-Serial communication serial debug the source code of aides, teacher" s own pen龚建伟

本程序调用了微软自带的mscomm控件，实现com口的数据接收，读者可自行添加发送数据功能。内附mscomm.ocx控件及其注册方法，本程序是用的静态链接库，为的是能在没有vc库的机器上也可以运行，所以个头大了点。-Microsoft"s own mscomm controls, I realize com data reception, readers can add their own functions to send data. Enclosing mscomm.ocx control and registration method, the procedure is used in the static link library, for the in the absence of vc for the machine can also run, giving the larger point.

简单的串口通信程序!通过按键来实验是否将主机中相应缓冲区中的内容传送给从机!主机状态改变,按键传输时,从机状态也将改变!-Simple serial communication program! Through the keys to the experiment whether or not to host the corresponding buffer content transmitted to the slave! Host state changes, button transmission, from the state machine will change!
