After reading this page, you should be able to understand most of the hardware and software protocol standards for RS If you have a chance to test your RS devices with the Analyzer software, you should be able to control your RS devices in a short period of time. A computer is a DTE. A modem is a DCE. However, that is not always true. If the voltage is on Pin 2, then it is a DCE device.

In depth analysis of your RS232 interface
One of the oldest, yet popular communication protocol that is used in industries and commercial products is the RS Communication Protoco l. The term RS stands for "Recommended Standard " and it is a type of serial communication used for transmission of data normally in medium distances. It was introduced back in the s and has found its way into many applications like computer printers, factory automation devices etc. In this article, we will understand the basics of the RS Protocol and how it works.
But still, RS has proven to be prominent. Moreover, it has better noise immunity. It is proven to be compatible across different manufacturers for interfacing computer and modems.
