RS232 is a serial information transfer protocol standard that defines both the protocol (method of transmission of data) and the physical hardware to do it. This document describes how it works at the physical level so you will know what signals you can expect to see at the microcontroller pi...
But since it is transmitted LSB (bit-0) first, the line toggles like that: 1-0-1-0-1-0-1-0. Here's another example: Here the data is 0xC4, can you see it? The bits are harder to see. That illustrates how important it is for the receiver to know at which speed the data is...

How it Works Serial Monitor works by installing a filter driver on top of a serial device driver. A filter driver intercepts all I/O requests issued by application. There are control requests that configure port parameters as well as data transfer requests that pass data between application and ...
