Question

我仍然在与AS3挣扎，但愿意尽可能多地学习。我正在尝试编写一个小样本flash应用程序，它将能够使用套接字类将变量发送到串行端口。我完成了我的作业，我知道闪存无法通过COM和USB等串口发送数据。为此，您必须使用一个程序，该程序将从Flash接收传出数据并将其发送到所需端口。 Arduino网站上描述了此类过程的最佳示例。从那里我了解到最好的方法是使用我已经下载并安装在我的Win7机器上的serproxy。我经历了这个问题的不同教程，我把fla应用程序放在一起，我认为它将完全符合我的要求。不幸的是，问题是即使应用程序连接到serproxy我也无法发送任何数据。

整个想法是能够控制通过USB或COM端口本地连接的简单设备。

正如您所看到的，我创建了一个按钮，可以使用端口5331建立和关闭与serproxy上的本地主机的连接。我还创建了按钮，它们应该通过套接字，字符串和整数发送两种类型的数据。不幸的是，他们都没有到达com端口。我已经检查了配置文件的serproxy并且设置正确，所以最后一个选项是我可能搞砸了AS3中的东西。我不知道它是否相关，但我在Flash播放器以及AIR 2.6中检查这一点 - 没有帮助。

我真的很感激任何帮助，如果有一个善良的灵魂可以启发我在整个剧本中出了什么问题。顺便说一句，很抱歉把剧本放在flash电影的第一帧 - 这就是我现在正在工作的方式 - 从来没有时间学习正确的方法，但是想尽快完成。

Answer 1

你的socket.flush() command在哪里？：）

这也是一种很好的做法。

socket.writeUTFBytes("This is a test for E" + String.fromCharCode(0) );

在大多数情况下，使用空字符结尾会有所帮助。

但是请记得在写完后再刷新插座。

Answer 2

我发现您的代码没有问题。除非第二帧是关键帧，否则没有任何东西会破坏它，在这种情况下，一旦你离开第一帧，第一帧中的套接字就会被破坏。（一般来说，时间轴代码旨在使图形设计人员更容易编写动画脚本。如果要保持更大的代码库，我建议您在单独的* .as文件中编写代码。

很少有尝试：Wireshark / tcpdump - 这些程序能够监控PC上所有端口的所有流量。通过使用它们，您至少可以看到发送的数据丢失的位置。至少为了实验，我会制作一个简单的TCP侦听套接字并尝试连接它以查看问题是否存在。

一般来说，尝试连接到并行端口或USB的其他东西很少 - 因为AIR 3有一个原生扩展选项（ANE），它是非常新的但是文档很少，但我宁愿一起去一，特别是如果用AS以外的语言写作不是问题。另一种与AIR运行时之外的另一个应用程序通信的方法是使用本机进程。即您将启动一个负责连接到您需要的端口/设备的应用程序，然后使用本机进程进行读/写，就像使用套接字连接一样。

Answer 3

我使用的组合是

socket.writeUTFBytes(myMessage);
socket.writeByte(0);
socket.flush();

我还建议进行调试
