摘　　要：介绍一种数字机顶盒串口升级的方法,此设计中包含了升级服务器端和机顶盒端两部分。在升级服务器端,采用了VC++6.0工具,以MSComm串口控件为底层接口,进行升级数据的传送;在机顶盒端,使用Linux的串口设备,对升级数据进行接收;同时,建立一个简单的串口通信协议(SPCP),以保证升级数据的准确传输。该升级方式主要用在机顶盒的研发和生产阶段,具有较强的目的性。This paper describes the method of digital set-top box by serial interface upgrade, and the design is composed of two parts, including server side and set-top box side, in the server side, withVC＋＋6.0 tools, andMSCommserial controls as the underlying interface for transmitting the upgrade data, while in the set-top box, with Linux serial device for receiving the upgrade data. Meanwhile, a simple serial port communication protocol （SPCP） is established, thus to ensure the accurate transmission of upgrade data. The upgrade mode, with a strong purpose, is mainly used in the development and production of set-top box.
