Inter-operation with RS-232 devices may be impossible as the serial port cannot withstand the voltage levels produced and may have other differences that ' the user to products of a particular manufacturer. Early home computers often had proprietary serial ports with pinouts and voltage levels incompatible with RS-232. Very low-cost systems, such as some early, would instead use the to send the data through an pin, using the technique.īefore (LSI) UART integrated circuits were common, a or would have a serial port made of multiple small-scale integrated circuits to implement shift registers, logic gates, counters, and all the other logic for a serial port.

This IC converts characters to and from form, implementing the timing and framing of data in hardware.

Hardware Some computers, such as the, use an called a.

A serial port requires very little supporting software from the host system.

Serial ports are still used in these areas as they are simple, cheap and their console functions are highly standardized and widespread. Network equipment (such as routers and switches) often use serial console for configuration. Computers may use a serial port as a control console for diagnostics. Serial ports are still used in applications such as industrial automation systems, scientific instruments, systems and some industrial and consumer products. Modern computers without serial ports may require serial-to-USB converters to allow compatibility with RS-232 serial devices. While such interfaces as, and all send data as a serial, the term 'serial port' usually identifies hardware more or less compliant to the standard, intended to interface with a or with a similar communication device. Throughout most of the history of, data was transferred through serial ports to devices such as modems, and various peripherals. In, a serial port is a interface through which information transfers in or out one at a time (in contrast to a ). Home Need Help?
