说明：  　一个嵌入式系统通常需要通过串口与其主控系统进行全双工通讯，譬如一个流水线控制系统需要不断的接受从主控系统发送来的查询和控制信息，并将执行结果或查询结果发送回主控系统。本文介绍了一个简单的通过串口实现全双工通讯的Java类库，该类库大大的简化了对串口进行操作的过程(an embedded system usually through its serial port control system for full-duplex communications, For example, a pipeline control system to accept the need to constantly sent from the main control system to control the inquiries and information, implementation will be the outcome or results of inquiries sent to the control system. This paper presents a simple realization through full-duplex serial communications Java class libraries, the library greatly simplifies the operation of the serial port for the process)
