I have just built the blacs library for RS6K workstations connected by 
thin wire ethernet. I have run the test subroutines and get output starting
as below. Does anyone have any documentation showing (a) exactly what the
testing routines are doing - what do the below numbers mean ? and (b) are
the below numbers good or bad (as I dont know what they mean I dont know
whether the installation is working well or not).
