1. A computer system including a host computer connected in a local area network (LAN), said LAN including said host computer and at least one other computer, the computer system comprising:
- first means for enabling said host computer to communicate with said at least one other computer using a predetermined standard protocol with a first LAN card; and
second means for enabling said host computer to communicate with a device external to said LAN by way of a second LAN card;
wherein said predetermined standard protocol is an internet packet exchange open data-link interface (IPXODI) protocol.

Abstract
Briefly, the present invention relates to a wireless interface device that can be interfaced to a wired local are a network (LAN) by way of a multiplexer which manipulates the source and destination addresses of the packets in order to be compatible with a standard protocol, such as IPXODI, which normally only supports a single LAN card.

8. A method for operating a computer system including a host computer connected in a local area network (LAN), said LAN including at least one other computer, comprising:
-
enabling said host computer to communicate with said at least one other computer using a predetermined standard protocol, said predetermined standard protocol adapted to support only a single LAN card, defining a first LAN card; and providing a second LAN card, for enabling said host computer to communicate with a predetermined device by way of a second LAN card in said host computer wherein, said first and second LAN cards are emulated as a single LAN card; wherein said predetermined standard protocol is an internet packet exchange open data-link interface (IPXODI) protocol. - View Dependent Claims (9, 10, 11, 12, 13, 14)

- 15. A computer system comprising, a host computer coupled within a local area network (LAN), said LAN including one other computer, said host computer configured to communicate within said LAN by way of a predetermined first protocol, said predetermined first protocol able to communicate with only a single LAN adapter, said host computer further configured to accommodate two or more LAN adapters and a second protocol, said second protocol for enabling each of said two or more LAN adapters to communicate within said LAN using said predetermined first protocol by enabling said second protocol to manipulate the addresses of each said two or more LAN cards to appear as a single LAN card to said first protocol, wherein said predetermined standard protocol is an internet packet exchange open data-link interface (IPXODI) protocol.

19. A computer system including a host computer connected in a local area network (LAN) having two or more LAN adapter cards, the computer system comprising:
-
a first communications protocol adapted to enable said host computer to communicate using a predetermined standard protocol, said predetermined standard protocol able to communicate with only one of said LAN adapters cards; and a second communications protocol adapted to enable said first communications protocol to support said two or more LAN adapter cards in said host computer, said second communications protocol adapted to interleave data from each of said two or more LAN adapter cards to emulate a single LAN adapter card; wherein said predetermined standard protocol is an internet packet exchange open data-link interface (IPXODI) protocol.
