Appeal No. 96-4169
Application 08/378,066
connect the keyboard and printer directly, a local mode, or to
connect the keyboard via the host computer to the printer 16,
an on-line mode.
Thus, Raasch is concerned with an interrupt driven
peripheral controller for use in an Industry Standard
Architecture compatible computer in order to minimize power
consumption. Galbraith, on the other hand, is concerned with
an asychronous buffered interface for interconnecting a data
processing apparatus adapted to communicate in serially coded
ASCII data format and a terminal comprising the printer and a
keyboard, both of which are adapted for data communication in
parallel format. We note that the Examiner has not explained
how Raasch's interrupt controller is to be modified by
Galbraith's keyboard-printer terminal interface. We fail to
find any reason
or suggestion to use the teaching of Galbraith in the Raasch
interrupt controller. Therefore, we will not sustain the
Examiner's rejection of claims 1 through 17, 19, 24 and 25.
Claims 9 through 17, 19 and 25 stand rejected under
11
