更新rmcpd为1.27.10版本后，进入DPU的SOL敲回车没反应，进入DPU SOL的命令如下：
ipmcset -t sol -d ac -v 5 0

主干版本为5.5分支，场内环境可复现。

当前日志信息只能看出来会话异常，一键收集的日志发送至邮箱 ouwenjian@huawei.com 吧。看描述是有两个问题，都发一份一键收集的日志吧。

一键式日志已发送，场内补发了问题2（rmcpd 1.27.10版本）的日志。

问题原因：在执行sol looptest过程中，在activate payload和deactivate payload切换间隙因从串口中读到数据返回给ipmitool工具，导致ipmitool端looptest流程出现失败。官方issue：https://github.com/ipmitool/ipmitool/issues/254
数据来源：os侧串口切换后根据/etc/issue返回的登录提示信息。
解决方案：
1、删掉/etc/issue下的登录提示信息。
2、looptest测试时，os下电。

实验了此方法，不行。使用了这个方法，删掉issue里面的内容，OS下电，默认的200圈sol looptest失败

根因同上，sol activate和deactivate间隙有sol数据返回客户端，导致客户端失败。已修改逻辑为先发送IPMI命令响应,再使能SOL发送,防止工具先收到SOL包,将SOL包作为命令响应。
