(test-lab)liuw@osstest:~/testing.git$ ./mg-hosts showprops | grep DTUART | grep 
arndale
 arndale-bluewater  XenDTUARTPath                  /serial@12C20000
 arndale-lakeside   XenDTUARTPath                  /serial@12C20000
 arndale-metrocentre XenDTUARTPath                  /serial@12C20000
 arndale-westfield  XenDTUARTPath                  /serial@12C20000
