CommandControl.CommandIndex 0 to 15 This array stores the command index within the
client ID. It can be determined by command row
number minus 1. Up to 16 command indexes can
be stored here
MBTCP.CONTROL.
CommandControl.CmdsAddedToQue This value is returned from the module. This is the
number of commands added to the queue.
-1 = Client not enabled and active.
