1 Introduction

RS-232 is a common point-to-point communication interface for various peripheral devices to enable communication between a host and a peripheral. RS-232 conforms to the TIA-232 and EIA-232 standards. To understand how to choose the correct RS-232 device for a system, a brief overview of the RS-232 standard as well key specifications for the transceivers is discussed in the following sections.
