再次从网上查询,搜到了RXTXcomm.jar包比较好,是封装了comm.jar的方法。
安装:
1.copy rxtxSerial.dll to [JDK-directory]\jre\bin\rxtxSerial.dll
2.copy RXTXcomm.jar to [JDK-directory]\jre\lib\ext\RXTXcomm.jar

为什么说乱码是中国程序员无法避免的话题呢?这个首先要从编码机制上说起,大家都是中文和英文的编码格式不是一样,解码也是不一样的!如果中国的程序员不会遇到乱码,那么只有使用汉语编程。汉语编程是怎么回事我也不大清楚,应该是前年吧,我一朋友给我介绍汉语编程,怎么不错不错?当时因为学习忙没去关注这个,等我闲 ......
