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。-Embedded systems often need a serial port full-duplex communication with host systems, such as a pipeline control system requires constant acceptance from the host system to send to the query and control information, and the implementation of results or query results sent back to the master system. This article describes a simple full-duplex communications through the serial interface Java class libraries, the library greatly simplifies the process of operation of the serial port.
