端口复用在系统已开放的端口上进行通讯，只对输入的信息进行字符匹配，不对网络数据进行任何拦截、复制类操作，所以对网络数据的传输性能丝毫不受影响
SAN需要的不再是一个简单的端口复用器，而是许多其它网络技术中提供的多种相同的扩展和弹性功能。
No longer a simple port multiplexer, a SAN requires many of the same scaling and resiliency capabilities offered in many other networking technologies.
在人机互动方面，采用改进型I/O端口复用键盘实现用户数据输入，使用两位数码显示管完成温度数据显示。
In the aspect of man-machine communication, we use the improved reused keyboard of I/O port to implement the users' data input, and displaying the temperature by two numeral displayers.
本发明提供了一种基于PCI总线的管脚复用的方法。该方法可以明显的减少PCI接口设备的端口数量，而且不需要大幅度增加电路的复杂度。
This invention provides a method for multiplexing pins based on PCI bus which can reduce port numbers of PCI interface equipments but does not increase complexity of adding circuits.
