BACnet Stack

I tried to read a BACnet Object Value from the Stack by using CMD and REPL. On REPL i get the value but u doesent seem to take the value in count

u=read(run(cmd /c set BACNET_IFACE=192.168.10.22 '&&' C:\\Users\\buehlpas\\Desktop\\bacnet-stack\\bacrp.exe 83 binary-output 2 change-of-state-count))

julia> u=readlines(run(cmd /c set BACNET_IFACE=192.168.10.22 '&&' C:\\Users\\buehlpas\\Desktop\\bacnet-stack\\bacrp.exe 83 binary-output 2 change-of-state-count ))
1070862
String

Any Idea?
