If you could always count on an endless stream of frames,one flag byte might be enough.But what if a frame ends (with a flag byte) and there are no new frames for 15 minutes.How will the receiver know that the next byte is actually the start of a new frame and not just noise on the line?The protocol is much simpler with starting and ending flag bytes.

如果您能总计数在框架一条不尽的小河,一个旗子字节也许是足够.但若架终端(以旗子字节) 并且那里是没有新框架15 分钟.接收器怎么知道,下个字节实际上是新框架和不仅噪声的开始在线?协议是简单以开始和结尾旗子字节
好象有点不通.哈哈
再试试

如果你总是依赖层出不穷框,说不定字节一面旗帜. 但如果时间结束(国旗字节),没有新的15分钟内. 如何接管知道下一字节是一个新的开始,而不仅仅是噪音范围为限? 该议定书是非常简单的始末,展开旗帜.
