java通过串口读取数据

最近要做一个项目，接口数据可能通过RS232串口给我们传过来，所以就事先学了一下java如何通过串口接收数据，怕自己忘了，所以记录下来。

java操作串口是通过RXTX实现的，可以从http://fizzed.com/oss/rxtx-for-java下载。

安装说明：

Windows

RXTXcomm.jar goes in \jre\lib\ext (under java)
rxtxSerial.dll goes in \jre\bin

Mac OS X (x86 and ppc) (there is an Installer with the source)

RXTXcomm.jar goes in  /Library/Java/Extensions
librxtxSerial.jnilib goes in /Library/Java/Extensions
Run fixperm.sh thats in the directory.  Fix perms is in the Mac_OS_X
subdirectory.

Linux (only x86, x86_64, ia64 here but more in the ToyBox)

RXTXcomm.jar goes in /jre/lib/ext (under java)
librxtxSerial.so goes in /jre/lib/[machine type] (i386 for instance)
Make sure the user is in group lock or uucp so lockfiles work.

Solaris (sparc only so far)
