在学习如何使用 Cisco 851W 路由器时，我下载了一个带有预配置设置的配置脚本。我从路由器运行了此脚本，但现在我无法再启动并进入命令提示符。
我尝试过在重新打开路由器时按住重置按钮，但我猜测闪存中没有有效文件，因为它会继续从 NVRAM 加载配置。
这是启动时的输出。在最后一行，它冻结了，我再也无法执行任何操作。有什么想法可以恢复吗？

答案1
使用此处说明的密码恢复方法，但不要恢复密码，而是删除启动配置。http://www.cisco.com/en/US/docs/routers/access/800/850/software/configuration/guide/857sg_bk.pdf
答案2
我最终发现 Putty 不允许我查看登录屏幕。我安装了 SecureCRT，登录提示立即出现。很奇怪，因为我在两个程序上使用完全相同的设置（9600 波特、8 个数据位、无奇偶校验、1 个停止位）。
