%
%	DIG_Out_Port sets the ouput value of a parallel digital i/o port on a National Instruments Card.
%	Before calling DIG_Out_Port you must once set the port direction to output using DIG_Prt_Config.  
%
%	deviceNumber-
%		The slot occupied by the card on which you want to set an outoptu port.  See Board_ID and 
%		FindCard functions to identify the card in a particular slot or to Find which slot a specified
%		card occupies.
%
%	port-
%		The number of the port which you want to set.  Remember, the first port is port 0, 
%		not 1.  For a three-port i/o card port numbers correspond to ports in this way:
%		0: PA
%		1: PB
%		2: PC
%
%	pattern-
%		The value written to the port.  Ports are eight-bits wide, so pattern must be in the range of
%		0-255.
