A connection between two computers locally, causing the computers to act as if connected via a modem. Generally used to transfer data from one machine to another.
A cable which interchanges wire positions, so that a DTE device looks like a DCE or vice versa.
Configuration that allows two DTEs to intercommunicate.
A short RS-232-C cable that connects two PCs so that they can communicate without the use of modems. The cable connects the two computers' serial ports, and certain lines in the cable are crossed over so that the wires used for sending data by the other computer, and vice versa.
A connection that is the equivalent of two modems wired back-to-back. Usually using a cable where several pins are cross wired from one end to the other, most notably so that the Send pair on one end of the cable is the Receiver pair on the other.
A device or cable wiring which eliminates the need for a modem in asynchronous transmission over short distances; generally connects receive to transmit, transmit to receive, and signal ground to signal ground.
A cable, especially an RS-232 cable, for connecting serial ports on two computers directly, rather than via modems. Since, according to the specification, both computers should transmit on pin three of their RS-232 connectors and receive on pin two, a null modem cable needs to connect one computer's pin two to the other's pin three and vice versa. It also needs to have male connectors at both ends (again, according to the specification).
Special cabling that eliminates the need for modems for asynchronous communications between two computers over short distances.
a cable that transmits information from your computer's communication port to that of your opponent's
a connection device that eliminates the need for the modems and phone networks between like devices (two DTE devices)
a device that allows one to connect two computers together, typically with only a serial port
a length of cable with the signal leads crossed so as to present a DCE interface
A cable used to enable two computers to communicate with each other by emulating a modem. The null modem cable is wired up so that the end connections from one to the other are: 2 connected to 3; 4 and 5 connected to 8; 6 connected to 20.
A serial communications term that indicates that the transmit data (TXD) and receive data (RXD) signals are crossed, or "nulled," in a cable, connector, or adapter. A null modem cable, connector, or adapter connects the TXD signal of one device to the RXD signal of another other device.
An adapter that enables two data terminals (DTE) or two computers (DCE) to be connected together.
A null modem link is a serial link to another computer directly through the use of a cable.
Synonym for modem eliminator.
There really is no "null modem" per se, but usually a null modem cable. This is a cable that connects two computers together via serial ports and allows...
See modem eliminator.
A device that connects two DTE devices directly by emulating the physical connections of a DCE device.
Small box or cable used to join computing devices directly, rather than over a network.
A simple form of modem connection where only the data interchange circuits, not the modem control circuits, are used.
Null modem is a communication method to connect two DTEs (computer, terminal, printer etc.) directly using a RS-232 serial cable. The original RS-232 standard only defined the connection of DTEs with DCEs i.e. modems. With a null modem connection the transmit and receive lines are crosslinked.
