Management Data Input/Output (MDIO), also known as Serial Management Interface (SMI) or Media Independent Interface Management (MIIM), is a serial bus defined for the Ethernet family of IEEE 802.3 standards for the Media Independent Interface, or MII. The MII connects media access control (MAC) devices with Ethernet physical layer (PHY ...
The High-Speed Serial Interface (HSSI) is a differential ECL serial interface standard developed by Cisco Systems and T3plus Networking primarily for use in WAN router connections. It is capable of speeds up to 52 Mbit/s with cables up to 50 feet (15 m) in length.
The USART's synchronous capabilities were primarily intended to support synchronous protocols like IBM's synchronous transmit-receive (STR), binary synchronous communications (BSC), synchronous data link control (SDLC), and the ISO-standard high-level data link control (HDLC) synchronous link-layer protocols, which were used with synchronous voice-frequency modems.
The Serial Line Internet Protocol (SLIP) [1] [2] is an encapsulation of the Internet Protocol [a] designed to work over serial ports and router connections. It is documented in RFC 1055 . On personal computers, SLIP has largely been replaced by the Point-to-Point Protocol (PPP), which is better engineered, has more features, and does not ...
Third-party applications can add this ability, such as the open-source com0com, freeware HW VSP3, or the commercial Virtual Serial Port Driver. Some virtual serial ports emulate all hardware serial port functionality, including all signal pin states, and permit a large number of virtual ports in any desired configuration.
Installable File System (IFS) – a filesystem API for IBM OS/2 and Microsoft Windows NT; Open Data-Link Interface (ODI) – network card API similar to NDIS; Uniform Driver Interface (UDI) – a cross-platform driver interface project; Dynax Driver Framework (dxd) – C++ open source cross-platform driver framework for KMDF and IOKit [16]
Most serial communications designs send the data bits within each byte least significant bit first. Also possible, but rarely used, is most significant bit first; this was used, for example, by the IBM 2741 printing terminal. The order of bits is not usually configurable within the serial port interface but is defined by the host system.
Interlaken is a royalty-free interconnect protocol.. It was invented by Cisco Systems and Cortina Systems in 2006, [1] optimized for high-bandwidth and reliable packet transfers. It builds on the channelization and per channel flow control features of SPI-4.2, while reducing the number of integrated circuit (chip) I/O pins by using high speed SerDes technology.
