A network switch having a unified, adaptive management paradigm for wireless network devices is disclosed. The switch includes configurable ports for connecting devices. A software application running on the switch allows a network administrator to selectively configure each port to support either a wired device or wireless device. Configuration information and software images that are needed for operation of the wireless device are associated with the port. When a wireless device is first plugged into the switch port, it downloads its configuration directly from the switch port. By storing the configuration information and images at the switch and automatically downloading them to the wireless devices, the task of configuring the devices is greatly simplified for the network administrator. This is particularly advantageous in heterogeneous network environments that support both wired and wireless devices, and where wireless device are readily moved to different ports.

A technique for reliable passage of handshaking information between a cellular modem and a land modem. Instead of bare transmission over a voice channel connection highly susceptible to signal fading and dropout, the initial modem handshaking exchange is instead FSK-encoded and broadcast using a network data signalling methodology already used to reliably pass signalling information between the base and registered mobiles. Automatic retransmission request signalling and transmission redundancy may be implemented to insure successful receipt at the receiving end of the radio link. Once received and verified, handshaking information is decoded and delivered to the destination modem in the appropriate format along cleaner fixed pathways. Reliable handshaking operations are contemplated whether the destination modem is a cellular modem registered in auto-answer mode (land-originated data call), or a land modem (mobile-originated data call). Backwards compatibility with non-compatible cellular fixed-ends or mobiles is maintained through extensive use of active acknowledgment messaging and software timed transactions.
