java jssc调制解调器发送msg
问题描述：
我想使用基于SIM900的单元调制解调器从Java/Netbeans发送文本消息。使用TeraTerm，我验证了我可以使用带有基本AT命令的调制解调器发送消息。以下代码尝试使用jssc发送消息。
我没有收到错误，数据似乎写入调制解调器，但我从来没有收到短信。对于电话号码，我已经尝试了+，没有。
在TeraTerm中，该号码必须没有+才能使用。已经尝试了许多变体，并且使用了许多变体。仍然没有取得进展。
我希望有人能看到我的方式的错误。java jssc调制解调器发送msg
在此先感谢。 Doug

答
我能回答我上面提出的问题。下面的代码工作。事件监听器不需要在那里。有帮助的主要变化是将新行和文件结尾定义为字节“public static final Byte eof = 0x1A，nl = 0x0D;”然后将这些字节与命令“serialPort.writeByte（nl）;”分开写入serialPort。我希望这可以帮助别人。
道格
PS：我写了一个Java类，可以简化使用JSSC发送代码到SIM900，如果有人有兴趣。
