Status Bits:When the In-use, Idle, Maintenance-busy, and 
Other-unavailable status bits are set to 1, a 
binary-encoded count corresponding to that 
status follows.
Counts:Bytes containing counts correlate with the 
status bits: The first count byte conveys the 
count for the highest order status bit set to 1. 
Typically, this is the “In-use” count, but it could 
be the idle count (for example). Later bytes 
convey the counts for the next highest order 
status...
