History of applications
Historically, RS-232 serial communication was used to interface computers to peripherals such as modems,
printers, keyboards, joysticks, and a mouse. Most of these applications have now converted to other
communication protocols such as the universal serial bus (USB).
Today, RS-232 serial communication is used in applications such as GPS, POS, glucose meters, barcode
scanners, automotive telematics, set-top boxes, gaming, and many others that require low-cost, low-speed
(sub 1Mbps) serial communication.
Evolution of the RS-232 IC design
Although the RS-232 transceiver design has evolved significantly, engineers can still use the RS-232 legacy
protocol in today's applications. RS-232 innovations are represented in Figure 2, and discussed in
chronological order below.
