Description

C3五号线QT-ISCS与FEP的CCTV接口
客户端sefepc与FEP服务端sefeps协议通讯假连接Resend重发起始命令和总召失败
导致CCTV命令无法下发至FEP
非立即重现问题，运行一段时间后会出现
重启FEP后问题临时解决
可能是sefeps协议对于接收到的Resend重发起始命令和总召，接收处理问题
附件是FEP用ehdc抓包的源码

FEP端的日志仅看到收到测试帧，未看到打印收到Resend重发起始命令和总召命令

分析源码无法解释上述问题：无论如何对于启动帧都会发送应答。看起来像是规约没有接收到任何信息，虽然ehdc显示接收到了。
微调了部分缺陷，后续再利用新的log机制观察。
