ABSTRACT:
A radio modem includes a serial interface adapted for connection to a host device via a wired serial link; a router coupled to the serial interface; a server coupled to the router; and RF transceiver coupled to the router. The router is configured receive data packets from the host device; identify whether an IP address of the packets match an IP address of the server; identify whether a cookie which identifies the predetermined type of protocol is contained in a cookie field of the packets; in response to identifying a mismatch between the IP addresses, or that the cookie is not contained in the cookie field, cause the packets to be routed to a server via the attachment with the cellular network; and in response to identifying a match between the IP addresses, cause the packets to be routed to the server.
