Using Java to realize serial port full duplex communication

An embedded system usually needs to carry out Full-duplex communication with its main control system, for example, a pipelined control system needs to continuously accept the query and control information sent from the master control system, and send the execution result or query result back to the master control system. This paper introduces a simple Java class library which realizes Full-duplex communication
