摘　　要：本文主要介绍Winsystems公司PCM-ESCC多协议串行通信卡在SDLC通信中的应用。文中主要包括:PCM-ES-CC多协议串行通信卡的功能,SDLC协议简介,Zilog 85230芯片简介,该卡在PC104平台下实现SDLC协议通信时的初始化程序设计、发送数据程序设计及接收数据程序设计等。测试表明,编写的程序实现了在PC104平台上通过扩展PCM-ESCC卡完成SDLC协议通信的功能。文中给出的硬件方案和软件设计方法可为基于PC104平台的设备实现SDLC通信时参考。The Winsystems PCM-ESCC Serial Controller Card and its application on SDLC protocol communication are introduced. The main contents are： the function of PCM-ESCC card, basic description of SDLC protocol and Zilog 85230 Serial Communications Controller, the program design for the initialization, transmitting and receiving data of this card extended on a PC104 computer. The test of the program indicated that the function of SDLC protocol communication can be used as achieved by the PCM-ESCC card running on a PC104 computer. The system design method of both hardware and software provided in this paper can be used as a reference of SDLC protocol communication solution for the PC104 computer.
