DSU/CSU Channel Service Unit/Data Service Unit

On the basis of an implementation of RFCOMM multiplex,this paper analyzes the implementation and utility property of the two kind (exclusive and shared) of emulated serial ports,pointing out that the shared mode not only saves the server channels for the server,but also enhances the success probability of the client s connection attempt.

文中在给出一种具体的RF COMM多路复用实现的基础上 ,对比分析了独享与共享两种仿真串口的实现方法及实用特性 ,指出共享实现方式具有节约服务器信道并提高客户连接成功率的优点。
