The serial DCD pin can be used to accurately detect a PPS signal, as described in RFC 2783: [1] One convenient means to provide a PPS signal to a computer system is to connect that signal to a modem-control pin on a serial-line interface to the computer. The Data Carrier Detect (DCD) pin is frequently used for this purpose.
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.
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 On personal computers, SLIP has largely been replaced by the Point-to-Point Protocol (PPP), which is better engineered, has more features, and does not ...
A null modem adapter. Null modem is a communication method to directly connect two DTEs (computer, terminal, printer, etc.) using an RS-232 serial cable.The name stems from the historical use of RS-232 cables to connect two teleprinter devices or two modems in order to communicate with one another; null modem communication refers to using a crossed-over RS-232 cable to connect the teleprinters ...
This communication is done via an Ethernet crossover cable as opposed to a PC to DCE (hub, switch, or bridge) communication which is done via an Ethernet straight cable. V.35 is a high-speed serial interface designed to support both higher data rates and connectivity between DTEs (data-terminal equipment) or DCEs (data-communication equipment ...
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]
Data Terminal Ready (DTR) is a control signal in RS-232 serial communications, transmitted from data terminal equipment (DTE), such as a computer, to data communications equipment (DCE), for example a modem, to indicate that the terminal is ready for communications and the modem may initiate a communications channel.
A rollover cable (also known as a Yost cable, Cisco cable, or a console cable) is a type of null-modem cable that is used to connect a computer terminal to a router's console port. This cable is typically flat (and has a light blue color) to help distinguish it from other types of network cabling.
