	Setting up handshaking in Configuring Ports
		The first four of the handshaking bitmasks control what type of flow control is obeyed when we are sending data.
		The most common form of flow control when receiving data is RTS handshaking (we lower our RTS output when we aren’t able to receive anything and then raise it when we are once again in a position to handle incoming data).
		For this reason, hardware flow control is the preferred handshaking method whenever there is a requirement for the transfer of binary data in either direction.

	Data flow control
		Handshaking is used when the NC cannot quickly process the received data.
		The method of exchanging signals between the NC and the DNC server is called handshaking.
		For hardware handshaking you will need a special cable for it is performed using special cables in this case.

	Hardware Handshake for 3Server COM Ports
		This handshaking is needed for the printer to tell the server that its buffer is full and can't accept any more data.
		Handshaking is accomplished by the exchange of control codes between the printer and the server via the transmit and receive lines, pins 2 and 3 respectively (RS232-C).
		XON/XOFF handshaking is adequate for most serial communication needs and can easily be set up on the server by selecting the correct parameters on the mode and 3mode lines.

	handshaking
		In the context of computers, handshaking indicates hardware or software to establish or maintain two machines or programs in synchronisation.
		Handshaking often requires the exchange of messages or packets of data between two systems.
		Hardware handshaking signals between two computers which are carried by voltage levels or pulses on wires.

	Plotter displays: INPUT BUFFER OVERFLOW message.
		Handshaking is an RS-232C communication protocol used to control data flow between a host and the plotter based on availability of buffer space.
		An overflow would occur if the plotter attempted to receive data from the host computer while it was still trying to process previous data, and the plotter had no place to store the incoming data.
		Hardware handshaking is referred to Direct Control on the plotters handshaking menu.

	[No title] (Site not responding. Last check: )
		Handshaking is a series of expect-send sequences that specify the initial communications that occur on a link before it is ready to send or receive data.
		Using the handshaking, the local and remote systems confirm that they are compatible and config- ured to transfer data.
		The handshaking characters include entries such as \d to specify a delay, \p for a pause, \r for a carriage return, and \c for a newline.

	Performing Digital Data Transfers in Visual Basic with NI 6533 Family Devices - Tutorial - Development Library - ...
		Handshaking protocols define how a buffer of digital data is transferred between two devices.
		In asynchronous handshaking, each device controls one control line that it uses to inform the other device that it is ready for data transfer.
		It is not a handshaking mode, but rather a method of transferring digital data at a predetermined frequency without control lines.

	Serial Port I/O (External Interfaces/API)
		Data flow control or handshaking is a method used for communicating between a DCE and a DTE to prevent data loss during transmission.
		When using software handshaking, the control characters are sent over the transmission line the same way as regular data.
		The main disadvantage of software handshaking is that you cannot write the Xon or Xoff characters while numerical data is being written to the device.

	handshaking - TunesWiki (Site not responding. Last check: )
		A term describing a simple synchronization scheme between two connected objects (programs, devices, or computer systems), which is usually designed to ensure that the two objects 'take turns' at communicating with each other.
		A classic example of handshaking is the line (wire carrying an electric signal) called 'DTR' of the RS-232 serial communications standard.
		Sometimes other handshaking protocols are used instead of the DTR line.

	Handshaking
		Handshaking refers to the internal communications protocol implemented in the computer hardware by which data is transferred from the modem to the communications port.
		Typically, the Data Terminal Ready signal is sent by a computer to its modem to indicate that the computer is ready to accept incoming transmission.
		Handshaking Type: A handshaking protocol is used so data is not lost when data arrives at the communications port.

	RS232 flow control and handshaking
		Handshaking is mostly used to prevent an overrun of the receiver buffer, the buffer in memory used to store the recently received bytes.
		RTS / CTS in its original outlook is used for handshaking between a computer and a device connected to it such as a modem.
		Although using this cable is not completely compatible with the original way hardware flow control was designed, if software is properly designed for it it can achieve the highest possible speed because no overhead is present for requesting on the RTS line and answering on the CTS line.

	Handshaking - Wikipedia, the free encyclopedia
		In telecommunication and microprocessor systems, the term handshaking has the following meanings:
		Note: Handshaking follows the establishment of a circuit between the stations and precedes information transfer.
		It is used to agree upon such parameters as information transfer rate, alphabet, parity, interrupt procedure, and other protocol features.

		A handshaking signal from the receiving device tells the transmitter "I am ready for data" or "I am not ready for data." These signals are optional: the receiver may always be ready for data or may choose to simply discard data it couldn't process.
		RTS/CTS handshaking and DTR/DSR handshaking are both referred to as hardware handshaking.
		Another form of handshaking, XON/XOFF or software handshaking, requires that the receiver send a character (Control-S, ASCII 19) to halt data transfer and another character (Control-Q, ASCII 17) to resume transfer.

	Handshaking Property (MSComm Control)
		Handshaking refers to the internal communications protocol by which data is transferred from the hardware port to the receive buffer.
		If there is no receive buffer and your program is expected to read every character directly from the hardware, you will probably lose data because the characters can arrive very quickly.
		A handshaking protocol insures data is not lost due to a buffer overrun, where data arrives at the port too quickly for the communications device to move the data into the receive buffer.

		Disable the use of DISTB/DIO7 as a handshaking pin, in turn freeing it for general I/O use.
		When input handshaking is enabled, rising edges on the DISTB input cause the Parallel Port data to be sampled and sent to the host in the form of a port receive message.
		When output handshaking is enabled, each data byte sent out the Parallel Port using the port send command will be accompanied by a positive DOSTB pulse lasting one IR sampling period.

	Handshaking (Definition)
		In telephone communication, handshaking is the exchange of information between two modems and the resulting agreement about which protocol to use that precedes each telephone connection.
		You can hear the handshaking in those crunching and other sounds when you make a dial-out call from your computer.
		Since the modems at each end of the line may have different capabilities, they need to inform each other and settle on the highest transmission speed they can both use.

	Handshaking Protocol
		The handshaking protocol establishes a secure session between WAP client and WAP gateway.
		The communication cost of handshaking is expensive because handshaking involves several rounds of signal information exchange.

	7.8 Handshaking
		Using status bits to indicate that a device is ready to accept or transmit data is known as handshaking.
		The system must complete the other half of the handshake operation and send the printer a signal to indicate that a byte is available.
		Bit zero (the strobe line) must be set to one and then back to zero when the CPU makes data available for the printer (the term "strobe" suggests that the system pulses this line in the command port).

	Monitor - #74 - RS232 Handshaking Explained
		The fact that your instrument comes equipped with inputs and outputs that can be used for handshaking is no guarantee that handshaking is needed.
		Hardware Handshaking ==================== Handware handshaking is not often used, so you can tie any potential handshake lines to fixed voltages so that they do not affect operation.
		If you do decide that handshaking must be used then you need to know which lines your communications software (such as COMIML) and your instrument use.

	Cable from console port to terminal (or another PC)
		The wiring within the null modem cable depends upon the handshaking and control signals that are needed.

	The RS232 Standard
		The handshake signals on each side are artificially made to appear asserted by the use of self-connects on each side of the cable (for example, between pins 4 and 5).
		Without hardware handshaking, you risk buffer overflow at one or both ends of the transmission unless STX and ETX commands are inserted in the dataflow by software.
		RTS and CTS are commonly used as handshaking signals to moderate the flow of data into the DCE device.
