Abstract: The transfer of data through a modem can be blocked in the modem during a safe mode unless the data includes predefined communications such as a request for a network address to maintain access to the network for the host system or a response to the request that includes the network address. Accordingly, the safe mode can protect a host system from unauthorized access from the network, while allowing the network service to be maintained for the host system. In particular, requests for renewals of leases, such as Dynamic Host Configuration Protocol (DHCP) requests and responses thereto, on Internet Protocol (IP) addresses used by the host system may not be blocked by the modem during safe mode. Furthermore, requests and response for addresses of systems on the network to which the DHCP requests are transmitted, such as Address Resolution Protocol (ARP) requests and responses thereto, may also not be blocked during safe mode.

Abstract: A carpet includes a weft fill material (18c) which fills the loops formed in the pile of warp yarns (14a and 14b) so as to be partially visible to contribute to both the design and appearance of the resultant carpet and the durability by supporting the inside of the loops formed by the warp yarns (14a and 14b). The binding chains (17a and 17b), with the wefts (18a and 18b), bind the pile warp yarns (14a and 14b) to the carpet backing with the stuffer (16) being held securely between the wefts (18a and 18b) . In alternative embodiments the binding chains (17a and 17b) can be partially or totally omitted with the warp yarns (14a and 14b) being fed over and under the stuffer (16). Apparatus for forming the carpet is described.
