获取USB调制解调器在java中连接的com端口

如何获取usb边缘调制解调器在java程序中连接的com端口。 neeed快速帮助。请告诉我使用哪个库来获取com ..除javax.comm外。我试过但失败了。我没有找到方法来正确安装它显示我错误conitneously。 :(获取USB调制解调器在java中连接的com端口

这是不是与USB相关的AT指令集等等......如果你已经仔细阅读错误消息，你就已经有了答案：

win32com.dll: Can't load IA 32-bit .dll on a AMD 64-bit.

主题是alredy解决此：Javax.comm API on 64-bit Windows
