Parity

The Parity parameter sets parity for odd, even or none. Under normal conditions, parity is set to none. The default is none.

Stop Bits

The Stop Bits parameter sets the number of stop bits. The number of stop bits can be 1, 1.5, or 2. The default is 1 bit.

Flow Control

The Flow Control parameter allows for two types of flow control: the software-based XON/XOFF and the hardware-based Clear to Send (CTS). The default is CTS. Flow control is the means by which data flow from the device into the MultiFRAD is controlled. Flow control is necessary when the data handling capacity of the data port cannot keep up with the volume of data sent to it. When the data device controls data flow to itself, it is called pacing (see Pacing). The combination of flow control from the port device and pacing to the data device is how data transfers are regulated so that no data is lost.

Pacing

The Pacing parameter controls the data flow to the data device. Pacing is necessary when the flow of data to a device operating on the data port is more than it can process. If the device cannot process the volume of data sent to it, then the pacing option should be turned on. The pacing method used is determined by the type of flow control. The default condition is for this option to be turned off.
