-/**
- * This class extends UnixLikeTerminal and implements the Cygwin-specific implementations. This means, running a Java
- * application using Lanterna inside the Cygwin Terminal application. The standard Windows command prompt (cmd.exe) is
- * not supported by this class.<p>
- * <p>
- * <b>NOTE:</b> This class is experimental and does not fully work! Some of the operations, like disabling echo and
- * changing cbreak seems to be impossible to do without resorting to native code. Running "stty raw" before starting the
- * JVM will improve compatibility.
