串口自动检测

Qt写的RS232串口程序源码,需要者收了吧(RS232 by Qt)

modbusRTU Communications with RS485

串口调试工具，包含自动计算MODBUS crc校验码，是工具非源码(tiaoshi gongju)

说明：  对松下FP系列PLC通讯串口的调试，了解串口使用的方法(Panasonic FP series PLC serial communications debugging of serial use)

用vb6.0做的一个小的串口测试程序.可以实现正常通信(Used vb6.0 to do a small test program serial)

RS-232 通信调试程序，初学者适应。(RS-232 communications debugger, beginners to adapt.)

说明：  自动识别电脑有多少个串口，关自动加载!!!(Automatically identify the number of serial computer, turn off automatic loading )

串口通讯调试代码，包括端口设置界面和信息收发界面(Serial communication debugging code, including port settings interface and messaging interface)

VB环境下简单的串口测试程序，测试两台主机通过串口是否能够实现数据传送，可以传送数字、字符串及汉字。(VB environment, a simple serial test program, test whether two hosts can be achieved through the serial data transfer, can send numbers, strings and characters.)

利用VB语言实现对串口进行操作，从而实现通过串口进行远程关机的操作，了解相关编程方法。(VB language serial port operation through the serial port for remote shutdown operation, understanding related programming methods.)
