SMSLib 备忘录

http://www.cnblogs.com/bluespot/archive/2008/08/02/1258735.html

    这是网上装载相当广泛的一篇关于SM Push的文章，里面提到了SMSLib的包，这是一个基于串口控制GPS Modem或者手机包，网上有相当多的介绍，摸索了一天，基本上学会使用了，备忘如下：

 

• 需要的第三方包，comm.jar，slf4j（slf4j-api-1.5.10.jar，slf4j-jdk14-1.5.10.jar，log4j-over-slf4j-1.5.10.jar），第一个是基于win32平台的串口控制包，后面是日志的，似乎可以搭配不同的log包使用没有深入学习。commons-net-2.0.jar据说需要，可能是用smpp使用到吧，我用串口的话似乎可以不用。
• 串口可以使com，usb甚至红外，蓝牙，我在5800I上用USB，实际上是com18，smslib里面有一段测试哪个串口连接了手机的类，可以试试

	private static Enumeration<CommPortIdentifier> getCleanPortIdentifiers()
	{

	}

				_formatter.format("%nFound port: %-5s%n", portId.getName());

				{

•  串口主要通过AT命令控制手机发送短信，关于AT命令和PDU的结构请参照下面的博客，作者搜集了相当多的资料

http://hi.baidu.com/dtzw/blog/category/Gsm

• 关于如何向手机指定端口发短信，我搜索了很多资料，可惜没有找到明确的指导资料，有几点要确认的：一般的Short Message Moden(这个关键词的中文居然被和谐了，无聊）和手机短信无法触发注册到特定端口的Midlet，端口数据其实没有写在PDU的结构数据中，而是写在写入短信体的UD中，关于UDHI（User Data Head Indicator）的结构网上没有找到资料，全部都是直接写入短信数据，要了解UDHI还是要自己查SMSLib的代码，它确实可以向指定端口发送短信，不过网上相当多的代码是旧版本的。
