 | 		units | 
 | 			Summary of all units present in an IEEE 1394 node. | 
 | 			Contains space-separated tuples of specifier_id and | 
 | 			version of each unit present in the node.  Specifier_id | 
 | 			and version are hexadecimal string representations of | 
 | 			u24 of the respective unit directory entries. | 
 | 			Specifier_id and version within each tuple are separated | 
 | 			by a colon. |
