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。:(

这与 USB、AT 命令等无关……如果您仔细阅读错误消息，您就会得到答案：

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

此方法对我有用。此代码将自动检测与 GSM 调制解调器连接的端口并发送 SMS。

    SerialModemGateway gateway = new SerialModemGateway("", "COM5", 9600, "", "");
    gateway.setInbound(true);
    gateway.setOutbound(true);
    OutboundNotification outboundNotification = new OutboundNotification();
    InboundNotification inboundNotification = new InboundNotification();
    Service service = Service.getInstance();
    service.setOutboundMessageNotification(outboundNotification);
    service.setInboundMessageNotification(inboundNotification);
    service.addGateway(gateway);
    service.startService();

    OutboundMessage msg = new OutboundMessage(num, massage);
    service.sendMessage(msg);
