获取在java中连接usb调制解调器的com端口

Question

如何在 java 程序中获取连接 USB 边缘调制解调器的 com 端口。需要快速帮助。 请告诉我使用哪个库来获取 com.. 除了 javax.comm。我试过但失败了。 我没有找到正确安装它的方法，它不断地向我显示错误。 :(

Answer 1

这与USB，AT命令等无关...如果您仔细阅读错误消息，您会得到答案：

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

话题已经在这里了：Javax.comm API on 64-bit Windows
