Description: 这是一个用89S52加PDIUSBD12模拟的一个U盘，里面涉及到USB接口，USB大容量存储设备，FAT16文件系统等内容。插入电脑后，可显示移动磁盘盘符及一个文本文件。
需要说明一下的是，这个包中的原理图，IDE接口部分、74HC573、以及RS232串口等部分，是作为这个实验板的一部分。在这个模拟U盘的程序中，是没有用到的。在下一个“移动硬盘”的例子中，就用到了IDE接口跟74HC573了。至于RS232，那时笔者在调试程序时用的。如果您不需要通过串口调试程序，RS232部分可以不管它。-This an increase PDIUSBD12 89S52 use of a simulation-U, they relate to the USB interface, USB mass storage devices, the FAT16 file system information. Insert a computer and can show that the mobile disk drive and a text file. The need to explain is that the package of schematics, IDE interface, 74HC573. RS232 serial port and other part of the experiment as part of the plate. In the U-simulation process is not to use the. Next a "mobile hard disk" examples, it uses an IDE interface with the 74HC573. For RS232, then the author debugging procedures used. If you do not need serial debugging procedures, RS232 can be part of it regardless.

Description: RS232串口技术文摘
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.
