Description: vb 串口通讯调试方法
现有电子秤一台，使用串口与计算机进行通讯。编写VB程序来访问串口，达到读取电子秤上显示的数据。该电子秤为BE01型仪表，输出为RS-232C标准接口，波特率为300-9600、偶校验、7个数据位、2个停止位。所有字符均发送11位ASCII码，一个起始位。在VB中与串口通讯需要引入控件MSComm串口通讯控件（在Microsoft Comm Control 6.0中）-vb serial communications debugging method existing electronic weighing a Taiwan, the use of serial communication with the computer. Preparation of VB to visit serial, electronic scales to read displayed on the data. The electronic scales for BE01-type instrument, the output of RS-232C standard interface, baud rate to 300-9600. Dual-checking, seven data bits, stop at two. All characters are sending ASCII 11, a starting place. In VB serial communications needs with the introduction of MSComm control serial communication controller (in Microsoft Co. Control 6.0 mm)

串口硬件标准：串行通信接口标准经过使用和发展，目前已经有几种。但都是在RS-232标准的基础上经过改进而形成的。所以，以RS-232C为主来讨论。RS-323C 标准是美国EIA(电子工业联合会）与BELL等公司一起开发的1969 年公布的通信协议。它适合于数据传输速率在0～20000b/s 范围内的通信。这个标准对串行通信接口的有关问题，如信号线功能、电器特性都作了明确规定。由于通行设备厂商都生产与RS-232C制式兼容的通信设备，因此，它作为一种标准，目前已在微机通信接口中广泛采用。
串口通信软件：随着计算机应用领域的不断扩展，计算机之间的远程通信用得也越来越广泛，计算机间的远程通信所使用的通信软件，在市面上可以买到，但是通用的通信软件虽然能发送和接收文件，在许方情况下这些通信软件并不能满足实际工作的需要。本文就这一技术进行了探讨，介绍了有关的知识和技术，并由实例分步骤说明如何进行通信软件的开发。-RS232 serial port technology digest
Standard serial port hardware: serial communication interface standard through the use and development, there are already several. However, RS-232 standards are based on the improved formed. Therefore, in order to discuss the main RS-232C. RS-323C standard is the U.S. EIA (Electronic Industries Alliance) and BELL and other companies announced in 1969 with the development of communication protocols. It is suitable for data rates in the 0 ~ 20000b/s within the communication. The standard serial communication interface issues, such as the signal line functions, electrical characteristics have been defined. As the production and access equipment vendors are standard RS-232C compatible communications equipment, therefore as a standard, currently in extensive use of computer communications interface.
