大家好,我想知道在4层TCP/IP协议栈和RS232通信之间是否有相似之处?我必须为基于PIC18的产品生成一个全面的文档,该产品在其RS232端口上连接到GSM调制解调器,以便与远程服务器通信。是否有可能使用TCP/IP使用的通用4层通信栈来解释这种通信的各个方面?我很感兴趣,因为我必须解释硬件电压水平,8位数据包格式,然后在RS232通信中使用的消息协议,以及这些东西是如何相互解耦的,一组人谁知道的服务器端技术,但没有。关于嵌入式设备,非常感谢您的帮助。
以上来自于百度翻译 以下为原文 Hello everyone I wonder if its possible to draw parallels between the 4-layers TCP/IP stack and RS232 communication? I have to generate a comprehensive documentation for a PIC18 based product which is connected to a GSM modem on its RS232 port to communicate with a remote server. Is it possible to explain the various aspects of this communication using the generic 4-layers communication stack which is used by TCP/IP? I am interested in it since i have to explain the hardware voltage levels, 8-bits data packets format and then message protocol used in the RS232 communication, as well as how these things are decoupled from each other, to a group of people who have good knowledge of server side technologies but not about the embedded devices. Your help is highly appreciated. |

一群对服务器端技术有很好了解的人可能对电压水平、解耦和诸如此类的事情一无所知。我甚至猜测他们对低级协议知之甚少。在他们看来,RS232连接看起来像一个已建立的TCP连接——全双工串行链路。
以上来自于百度翻译 以下为原文 A group of people who have good knowledge of server side technologies probably know nothing about voltage levels, decoupling and this sort of things. I would even guess they know very little about low level protocols. In their mind, an RS232 connection will look like an established TCP connection - full duplex serial link. |
