摘要： 以ARM7系列的S3C44B0X微处理器和RTL8019AS网络接口芯片等构建嵌入式系统，移植uClinux，并在RH Linux 9.0和uClinux为ARM处理器提供的交叉开发工具下，完成基于TCP/IP协议的串口/以太网数据转换设备的开发。该设备支持服务器和客户机模式，为传统串口设备通过标准TCP/IP协议接入Internet提供了一种低成本解决方案。目前该设备已在某机械制造公司得到初步应用。

Abstract: Embedded system based on ARM7 MCU S3C44B0X and network interface chip RTL8019AS is developed, on which uClinux operation system is ported. Serial port/Ethernet data transfer device through TCP/IP protocol is developed under RH Linux 9.0 and uClinux cross development tools for ARM. Server and client mode are supported. It provides a low-cost solution for traditional serial-interfaced equipment to connect with the Internet. This device has been put into use in a mechanical manufacturing company.
