US Patent:

6665724, Dec 16, 2003

Filed:

Jul 20, 1999

Appl. No.:

09/357803

Inventors:

Thomas David Lawrence - Mission Viejo CA

Assignee:

Canon Kabushiki Kaisha - Tokyo

International Classification:

G06F 1516

US Classification:

709230, 709220, 709222

Abstract:

A network interface device that is capable of supporting a plurality of protocols on a heterogeneous LAN, and that triggers the initialization of at least one loaded, but uninitialized, protocol stack upon the automatic detection of a network communication on the LAN that is supported by the protocol stack. The network interface device is also capable of triggering the initialization of at least one loaded, but uninitialized, protocol stack upon the receipt of a network services or status request from an application software module that requires the support of the protocol stack.

International Classification:

H04N 7/18

US Classification:

725 81

Abstract:

A method for configuring a device using a remote control, includes transmitting a signal from the remote control to a configuration proxy requesting configuration status of the device; waiting for a predetermined period of time for a response from the configuration proxy to the remote control; obtaining help information based on the response received at the remote control from the configuration proxy; and displaying the help information on a display.

International Classification:

G06F 1300

US Classification:

3952005

Abstract:

A method for dynamically determining a media type of a LAN to which a network device is connected, includes executing at least one network interface driver which supports a predefined network media type, and which has one or more configuration tables and one or more logical boards for processing communication packets having different frame types. Each configuration table is associated with one of the boards, which each includes a frame type identifying value that identifies a combination of frame type and media type for packets processed by the corresponding board. A multiplexer software module is executed, which interfaces between the network interface driver and one or more protocol stacks, and which routes packets from the network interface driver to respective protocol stacks. An executed protocol stack obtains an entry point of a network interface driver service routine via the multiplexer software module, obtains a location for one of the configuration tables via the service routine, reads the frame type identifying value in the one configuration table, and determines the network media type of the network interface driver by comparing the frame type identifying value read from the one configuration table to one or more values that correspond to a predetermined media type.
