Description: 使用Delphi7、SPComm控件写的一个简单串口调试助手，把源代码分享给大家，在Delphi7环境下调试通过。程序可设置CoM端口，波特率、数据位、校验、停止位等，点击“打开串口按钮”，即可看到状态。-Using Delphi7, SPComm controls write a simple serial debugging assistant, the source code for everyone to share in Delphi7 through debugging environment. Program can be set CoM port, baud rate, data bits, parity, stop bits, etc., click on the " button to open the serial port" , you can see the status. Platform: |

Description: 根据SPCOMM进行改进的，最适用于delphi 2006，当然DELPHI7也行，至于 2007以后的unicode格式的，估计就不支持了。增加了获取串口列表的函数功能。很方便 。-According to the SPCOMM to improve, the most suitable for Delphi 2006 Platform: |

Description: 支持Delphi7/XE7 为控件增加应答方法。新增两个属性：ResponseDelay 应答延时、ResponseRetry 重试次数。 DisposeRpsData 首先应实现事件。在该事件中，通过发送和接收到的数据判断并处理应答信息，返回True表示接收数据为应答数据；返回False则表示接收数据不是有效数据，该数据将重新返回消息队列由 ReceiveData 方法处理。 ResponseComm 方法实现应答模式调用。它首先写数据到串口，等待串口的返回数据，如果超过应答延时，将重新写数据到串口，直到达到重试次数。如果串口有数据返回，调用 DisposeRpsData 事件，由该事件判断回答事件是否成功。 该方法将会堵塞进程-Support Delphi7/XE7 for the control to increase the response method. Add two attributes: ResponseDelay response delay, ResponseRetry retry count. DisposeRpsData should first implement the event. In this event, the sent and received data to determine and process the response information, return True that the received data for the response data return False means that the received data is not valid data, the data will be returned to the message queue by the ReceiveData method. The ResponseComm method implements the reply mode call. It first write data to the serial port, waiting for the serial port to return data, if more than the response delay, will re-write data to the serial port until the number of retries. If the serial data is returned, call the DisposeRpsData event, which the event determines whether the event was successful. The method will block the process Platform: |

Description: 不借助其它底层Modbus控件，直接操作底层通讯代码，实现Modbus读写“保持寄存器”数据，支持串口通讯、TCP通讯两种方式。代码只作演示，可做进一步封装，也可稍作修改，用于非标准的Modbus通讯。本代码使用了一个第三方控件SPComm，开发测试环境为Delphi7+Win7，我一直想摆脱Modbus控件(MBAXP Modbus Master ActiveX Control
)，最近自己开发了这个DEMO，分享给大家。(Without other underlying Modbus controls, the direct operation of the underlying communication code, the realization of Modbus read and write, "keep register" data, support for serial communication, TCP communication two ways. The code is for demonstration only, can be further encapsulated, and can be modified slightly for nonstandard Modbus communications. This code uses a third party control SPComm, development test environment for Delphi7+Win7, I always want to get rid of Modbus control (MBAXP Modbus Master ActiveX Control
) recently developed this DEMO and shared it with you.) Platform: |
