Because of its serial communication line is simple, convenient, widely used in many fields. This paper mainly introduces how to design and realize the WINDOWS operating system is running the communications between PCS. Using the java language applicate this software, APC220-43 as wireless transceiver, realizing the communications between PCS, this design undertake graphic interface operation. This software USES the Javax.comm bag, it is used for development platform independent communications applications extension-api. Data stored in the data access in MySql database, use Hibernate framework. And the serial data flow of homemade packaging tool, convenient for the control and serial
This paper describe serial port and the use of javax.comm in detail.Write and test this software in gear.
