Note: You must specify the same unit address for devices from different logical partitions to communicate with each other. In this example, device 100 in LPAR1 can communicate with device 200 in LPAR2. Also, device 110 in LPAR1 can communicate with device 210 in LPAR3. This example assumes that the application program supports send and receive functions on a single device number.
