The CommandFrame type exposes the following members.

Constructors

	Name	Description
	CommandFrame(SerializationInfo, StreamingContext)	Creates a new CommandFrame from serialization parameters.
	CommandFrame(UInt64, DeviceCommand)	Creates a new CommandFrame from specified parameters.
	CommandFrame(Byte, Int32, Int32)	Creates a new CommandFrame from the given buffer.

Remarks

IEEE 1344 command frames are designed only to be sent to a device, not received from a device. As a result this frame does not implement ISupportFrameImageTTypeIdentifier for automated frame parsing. This class exposes a constructor that accepts a binary image in order to manually parse a command frame.
