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 ...
In telecommunication and data transmission, serial communication is the process of sending data one bit at a time, sequentially, over a communication channel or computer bus. This is in contrast to parallel communication, where several bits are sent as a whole, on a link with several parallel channels. Serial communication is used for all long ...
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 ...
RS-422. RS-422, also known as TIA/EIA-422, is a technical standard originated by the Electronic Industries Alliance, first issued in 1975, that specifies electrical characteristics of a digital signaling circuit. It was meant to be the foundation of a suite of standards that would replace the older RS-232C standard with standards that offered ...
COM (hardware interface) COM port ( DE-9 connector). COM (communication port) [ 1][ 2] is the original, yet still common, name of the serial port interface on PC-compatible computers. It can refer not only to physical ports, but also to emulated ports, such as ports created by Bluetooth or USB adapters .
Serial cables are typically used for RS-232 communication. A serial cable is a cable used to transfer information between two devices using a serial communication protocol. The form of connectors depends on the particular serial port used. A cable wired for connecting two DTEs directly is known as a null modem cable.
Appearance. This is a list of interface bit rates, is a measure of information transfer rates, or digital bandwidth capacity, at which digital interfaces in a computer or network can communicate over various kinds of buses and channels. The distinction can be arbitrary between a computer bus, often closer in space, and larger telecommunications ...
PuTTY user manual (copy from 2022) PuTTY ( / ˈpʌti /) [ 4] is a free and open-source terminal emulator, serial console and network file transfer application. It supports several network protocols, including SCP, SSH, Telnet, rlogin, and raw socket connection. It can also connect to a serial port. The name "PuTTY" has no official meaning.
