通过Java将命令发送到telnet时触发循环问题

Question

我一直在构建工具，使我和我的团队能够在我们的测试套件上执行许多日常任务。我们有许多耕种控制器，使我们能够执行诸如存储打开和存储关闭之类的任务，并且有人要求我尝试做一些可以按计划远程执行的操作，这样我们的环境团队就不必搞乱了修复由于使用不当而造成的问题。

该程序的核心不是我自己的代码，因为我对telnet的概念还很陌生，有人为我做了艰苦的工作。

我可以发送命令，直到在打印流中出现某些提示之前，我的问题是出现在处理不同的屏幕提示上，这些提示对于任何一个控制器都可能出现或不出现（有些直到未启用，有些出现打印机问题-所有这些都由控制器上的错误消息和按F键退出或继续操作的F键处理。

我可以使用if循环捕获第一个潜在消息，但就我的一生而言，我不知道如何处理第二个潜在消息。

到目前为止，我已经将代码粘贴到了下面（对于任何明显的不良做法，我们深表歉意。我目前可以随意使用它，而无需任何铅支持，因此如果您愿意提供它，我会征求一些意见:)）< / p>
