我正在开发一个 Java 应用程序来使用 USB 调制解调器发送短信（我的是华为 E173）。我尝试了 SMSLib，它的示例代码成功发送了短信。但是当它连接到互联网时，它会给出异常

org.smslib.GatewayException: Comm library exception: java.lang.RuntimeException: javax.comm.PortInUseException: Port currently owned by Unknown Windows Application
    at org.smslib.modem.SerialModemDriver.connectPort(SerialModemDriver.java:102)
    at org.smslib.modem.AModemDriver.connect(AModemDriver.java:114)
    at org.smslib.modem.ModemGateway.startGateway(ModemGateway.java:189)
    at org.smslib.Service$1Starter.run(Service.java:277)

有没有办法在连接到互联网时发送短信？我是否必须通过我的 Java 应用程序本身建立连接，如果需要，如何建立？

编辑：这是我发送短信的完整代码（从 smslib.org 下载，我更改了 SMSC 号码和发件人号码） 

// SendMessage.java - Sample application.
//
// This application shows you the basic procedure for sending messages.
// You will find how to send synchronous and asynchronous messages.
//
// For asynchronous dispatch, the example application sets a callback
// notification, to see what's happened with messages.

如果调制解调器正在用于“连接到 Internet”，则已经有一个电话正在进行中。然后你不能用它来拨打第二个号码来发送短信。可能的解决方案：

  1. 使用不同的方法连接到互联网，释放调制解调器
  2. 获得第二条电话线和第二个调制解调器
  3. 使用电子邮件到 SMS 服务并通过 Internet 通过电子邮件发送消息。例如，对于 AT&T，您可以向 [phone-number]@txt.att.net 发送电子邮件以向手机发送 SMS。

如果您正在尝试专门调试通过调制解调器发送 SMS 的程序，那么选项 1 或 2 可能是唯一的解决方案。
