These make it possible to connect devices that would not have operated feasibly over slower serial connections, such as mass storage, sound, and video devices.Many personal computer motherboards still have at least one serial port, even if accessible only through a. 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.Low-cost processors now allow higher-speed, but more complex, serial communication standards such as and to replace RS-232. Before (LSI) UART integrated circuits were common, a 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.Early home computers often had proprietary serial ports with pinouts and voltage levels incompatible with RS-232.
