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 16Page: Previous 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 NextLast modified: November 3, 2007
