          Appeal No. 95-5030                                                          
          Application 07/815,694                                                      



               Responding to the appellants' argument, the examiner stated            
          (supp. answer at 6):                                                        

                         First, such a signal designating an                          
                    initiation of a transfer is well known in the                     
                    art of I/O processing which is known as                           
                    "handshaking".  Furthermore, in a networking                      
                    environment such handshaking is pefromed                          
                    [sic, performed] at the data link layer by                        
                    sending supervisory frame to initiate a                           
                    transfer which is essentially the same thing                      
                    as saying "I have something to send, are you                      
                    ready".  As claimed, such limitations are not                     
                    distinct from interface(s) to a plurality of                      
                    input units to a computer terminal for                            
                    inventory management.  Such a system would                        
                    use normal protocol for sending the                               
                    appropriate signals to initiate a transfer.                       
                    Thus, any interface would receive a ready                         
                    signal from an input unit to relay a signal                       
                    to the receiving unit (i.e. computer terminal                     
                    through the interface "interconnect                               
                    circuitry") the sending unit has something to                     
                    send.  Sakon et al teaches such a system.                         
                         In addition, because of a lack of                            
                    distinctions in the claims, the data                              
                    processing device taught by Sakon et al is                        
                    construed as a receiving unit (second device)                     
                    connected to a plurality of input devices                         
                    through an interconnect circuitry (nos. 6-8,                      
                    Fig. 1).  When the data processing device                         
                    determines that there is a presence/absence                       
                    of data in memory unit 11 such a deter-                           
                    mination can be construed as sending a signal                     
                    [from] a first device to a second device.                         

               Thus, it is evident that in the supplemental examiner's                

                                          16
