A USB-to-serial adapter or simply USB adapter is a type of protocol converter that is used for converting USB data signals to and from serial communications standards ( serial ports ). Most commonly the USB data signals are converted to either RS-232, RS-485, RS-422, or TTL-level UART serial data. The older serial RS-423 protocol is rarely used ...
RS-232. A DB-25 connector as described in the RS-232 standard. Data circuit-terminating equipment (DCE) and data terminal equipment (DTE) network. In telecommunications, RS-232 or Recommended Standard 232 [ 1] is a standard originally introduced in 1960 [ 2] for serial communication transmission of data. It formally defines signals connecting ...
Serial port. A male D-subminiature connector used for an RS-232 serial port on an IBM PC compatible computer along with the serial port symbol. A serial port is a serial communication interface through which information transfers in or out sequentially one bit at a time. [ 1] This is in contrast to a parallel port, which communicates multiple ...
The eXtensible Host Controller Interface ( xHCI) is a technical specification that provides a detailed framework for the functioning of a computer's host controller for Universal Serial Bus (USB). Known alternately as the USB 3.0 host controller specification, xHCI is designed to be backward compatible, supporting a wide range of USB devices ...
The drivers for a software-implemented modem create a virtual serial port for communication with the host operating system, since the modem is implemented entirely in the device driver and therefore there is no point where the serial data would be sent to the physical card.
BNU is a high-performance communications device driver designed to provide enhanced support for serial port communications. The BNU serial port driver was specifically targeted for use with early (late 1980s - 1990s) DOS -based BBS software. The reason for BNU and other similar enhanced serial port drivers was to provide better support for ...
Input/output. v. t. e. In the context of an operating system, a device driver is a computer program that operates or controls a particular type of device that is attached to a computer or automaton. [ 1] A driver provides a software interface to hardware devices, enabling operating systems and other computer programs to access hardware ...
FTDI. Future Technology Devices International Limited, commonly known by its acronym FTDI, is a Scottish privately held fabless semiconductor device company, specialising in Universal Serial Bus (USB) technology. [1] It develops, manufactures, and supports devices and their related cables and software drivers for converting RS-232 or TTL serial ...
