@ Argument 
card_number:  The card number of the PCI-7300A card. 
@ Return Code 
NoError 
PCICardNumErr 
PCICardNotInit 
5.17  _7300_GetOverrunStatus 
@ Description  
When you use 
_7300_DI_DMA_Start
 to input data, the input data is stored

@ Description  
The function will perform digital output N times with DMA data transfer. It will 
takes place in the background which will not be stop until the Nth conversion 
has been completed or your program execute 
_7300_DO_DMA_Abort
function to stop the process. After executing this function, it is necessary to
