Multi-Drop Protocol


     Used when connecting multiple readers to a
     INTERMEC 9154 Controller or a 9161A Option 02
     Multi-Drop Concentrator.  Multi-Drop protocol is
     similar to Polling Mode D; however, in Multi_drop,
     each device on the line is assigned a unique POL
     and SEL character.  Multi_Drop operates only at
     2400 BAUD or higher, and its data communication
     protocol can't be modified.
