Computer-executable process steps according to claim 49, wherein the computer uses one of an IPX/SPX protocol, a TCP/IP protocol, and an AppleTalk protocol, and wherein the address data identifying the packet formed by the forming code as a configuration packet is (i) a predetermined socket, when the computer uses an IPX/SPX protocol, (ii) a predetermined port, when the computer uses a TCP/IP protocol, and (iii) a predetermined DDP type, when the computer uses an AppleTalk protocol.
Claim 61
Dependent Claim 79 words
Computer-executable process steps according to claim 47, wherein the inputting code includes code to input data indicating whether the new configuration information should be implemented immediately or at the next initialization of the network interface device and, when the input data indicates that the new configuration information should be implemented immediately, the forming code sets data in the configuration packet indicating that the network interface device should execute an initialization process using the configuration information in the configuration packet.
Claim 62
Dependent Claim 67 words
Computer-executable process steps according to claim 47, wherein the network interface device includes a peripheral server; and wherein the computer-executable process steps further comprise: code to form a packet including destination address information identifying the network interface device, address data identifying the peripheral server, and data to be serviced by the peripheral server; and code to transmit the packet to the network interface device via the LAN.
