我的代码仍在工作，我可以发送消息并等待消息发送。发送消息的持续时间大约为 10 秒，这对我不利，因为我的程序在发送下一条消息之前需要 1 秒的间隔。看看以澄清问题。

msg4 -> msg3 -> msg2 -> msg1

msg4、msg3 和 msg2 仍在等待，直到 msg1 已发送/失败。

这是代码sendMessage.java

    public void doIt(String mobile_number, String message) throws Exception
    {
            OutboundNotification outboundNotification = new OutboundNotification();
            System.out.println("Example: Send message from a serial gsm modem.");
            System.out.println(Library.getLibraryDescription());
            System.out.println("Version: " + Library.getLibraryVersion());
            SerialModemGateway gateway = new SerialModemGateway("modem.com5", "COM5", 921600, "", "");
            gateway.setInbound(true);
            gateway.setOutbound(true);
            Service.getInstance().setOutboundMessageNotification(outboundNotification);
            Service.getInstance().addGateway(gateway);
            Service.getInstance().startService();
            System.out.println();
            System.out.println("Modem Information:");
            System.out.println("  Manufacturer: " + gateway.getManufacturer());
            System.out.println("  Model: " + gateway.getModel());
            System.out.println("  Serial No: " + gateway.getSerialNo());
            System.out.println("  SIM IMSI: " + gateway.getImsi());
            System.out.println("  Signal Level: " + gateway.getSignalLevel() + " dBm");
            System.out.println("  Battery Level: " + gateway.getBatteryLevel() + "%");
            System.out.println();



            OutboundMessage msg = new OutboundMessage(mobile_number, message);
            Service.getInstance().sendMessage(msg);

            System.out.println(msg);
            System.out.println("Now Sleeping - Hit <enter> to terminate.");
          //  System.in.read();
            Service.getInstance().stopService();
    }

在我的main.java类中

for(int i=0; i<4; i++) {
  new sendMessage().doIt("09483221***","This is the message");
  Thread.sleep(1000);
}

第一条消息已成功发送，但第二条消息未发送，依此类推。如何让这些等到发送第一条消息？

一旦您发送第一条消息，您的端口就无法用于下一条短信，这就是为什么您无法发送第二条短信的解决方案一旦发送您的第一条短信，就终止端口并发送第二条短信
