Appeal No. 2000-0883
Application No. 08/672,528
implemented applications running in said environment that employ
different memory addressing modes, comprising:
a device driver coupled to said operating system environment
and having application program interface to communicate with said
applications through a set of predefined function calls;
said device driver having a message handler responsive to
said function calls and a message buffer to establish buffered
communication between at least two of said applications, one
application being a sending application and one application being
a receiving application, the sending application issuing
predetermined information intended for the receiving application;
a mapping mechanism coupled to said message handler
configured to determine the addressing mode of said sending
application and to translate the addressing mode of said sending
application into a predetermined addressing mode;
a message transfer mechanism coupled to said message handler
that uses said mapping mechanism to copy said predetermined
information into said message buffer and then to signal said
receiving application to access said message buffer to copy said
predetermined information,
whereby a copy of said predetermined information is passed
between sending application and receiving application without
requiring the receiving application to know the addressing mode
of the sending application whereby the sending application is
adapted to operate asynchronously of the receiving application.
The prior art references of record relied upon by the
examiner in rejecting the appealed claims are:
