摘　　要：本文阐述嵌入式RS232／Internet网关的硬、软件设计和实现。首先介绍网关的功能;其次介绍以单片机和以太网控制器RTLS019AS为核心搭建的硬件结构;最后详细介绍了软件设计。嵌入式网关主要完成具有RS232接口的设备通过Internet传送数据的问题。Design and implementation of hardware and software of embedded RS232/Internet gateway are expatiated explicitly. First,functionsof gateway are introduced. Then, hardware platform is established with single chip computer and RTL8019AS as its core. Finally, software design is introduced in detail. Using this gateway, serial devices with RS232 interface can transmit data through Internet.
