ecp(extended capabilities port meaning in Chinese

延长能力端口

The system abandons the serial communication that is low speed and low effect , but change to use the printing port , realizes the high speed , efficient parallel communication , further more choose to use to the ecp ( extended capabilities port , ) mode of parallel communication . according to the outside physical transfer ability , this mode can automatic adjust the transfer speed , and realize the data communication with the arbitrary speed
该系统在上下位机的数据传输中，摒弃了低速、低效的串行通讯，而改用打印口，实现了高速、高效的并行通讯，并且选用了并口的ecp （ extendedcapabilitiesport ,扩展功能接口）模式，可以根据外设的实际传输能力自动调整传输速度，实现任意速度的数据通讯。
