我从工作单位买了一台 Sunfire v215 服务器（他们正在回收它），以便在业余时间摆弄它。我正试图启动它 - 安装指南说您需要使用串行终端或终端仿真器（目前使用 putty）来访问 SC/ALOM。
我正在使用 USB 转 DB9 转换器和 DB9 转 RJ45 以及直通电缆连接到机器上的串行管理端口。
启动服务器后，我能够在控制台中看到输出，但机器似乎没有收到我的任何命令。
输出如下：

几分钟后，无论我如何输入，系统都会超时，只剩下以下内容：
Serial line login timeout, returns to console stream.
Enter #. to return to ALOM
什么原因导致串行连接表现得像“只读”？
