RS-232: Serial Interface
RS-232 is a serial communication standard that, despite its age, still has a variety of uses in today's digital landscape. This article dives into the intricacies of RS-232, starting with a basic understanding of what it is, followed by its pin assignments, V.24 and V.28 interfaces, and an explanation of the Null Modem concept.
RS-232: Connectors and Cabling
RS-232 defines the meaning of the different serial signals and their respective pin assignments on a standard 25-pin (DB-25) serial connector. Table 1 (a plain text version is also available) shows these assignments. Luckily, in standard types of communications only 9 of these pins are important: 1-8, and 20.
RS232 Pinout / EIA232 Pinout and signal assignments
RS232 Pinout. The RS232 specification only defines the pin-out for a 25 pin D connector; how ever, the 9 pin is used more often (defined by EIA-574). The serial port found on Personal Computers uses a 9-pin connector. Normally the RS232 serial port is used for external modems, and in older systems for the mouse and printer interfaces.
RS-232
The resulting common problems were non-standard pin assignment of circuits on connectors, and incorrect or missing control signals. ... PCI Express x1 card with one RS-232 port on a nine-pin connector. In the book PC 97 Hardware Design Guide, Microsoft deprecated support for the RS-232 compatible serial port of the original IBM PC design.
Serial Port I/O (External Interfaces/API)
Serial Port Signals and Pin Assignments. Serial ports consist of two signal types: data signals and control signals. To support these signal types, as well as the signal ground, the RS-232 standard defines a 25-pin connection. However, most PC's and UNIX platforms use a 9-pin connection. In fact, only three pins are required for serial port ...
