摘要
话带MODEM是分布式系统中实现点对点通讯的理想方式,背靠背方式的连接不同于公用电话网的使用环境,需要重新考虑握手的方式,特别是对于分布式实时控制系统如何建立快速的握手机制是一个关键的问题。文章介绍了一种建立快速连接的方式,可用于任何利用电话线、双绞线、被复线、导线连接的专用系统中。
Voice band MODEM is an ideal tool to realize point-to-point data communication in distributing system. The MODEM used in back-to-back connection is different from the one used in Public Switched Telephone Network.A new handshaking techniqul is demanded.Especially, it is critical to establish quick connecting in distributing real-time system .In this paper, I introduce a technique to realize quick connecting. It can be used in any special data communication system linked by twisted-pair or telephone lines.
