Abstract: A laptop computer contains a built-in modem and has a phone jack for connection to a telephone line while the computer is being operated in a stand-alone mode. A docking station into which the laptop computer may be docked allows the combined unit to be operated in a desk-top mode. The docking station may have a full-sized keyboard and display so that the laptop functions as the main computer a user may employ in the office or home. A telephone connection is already in place at the docking station so that the user need not make a phone line connection to invoke the docked mode, but instead merely nests the laptop in the docking station. In one embodiment, the only components of the modem that are duplicated in the docking station are the phone jack itself and an isolation and 2-to-4 wire converter, so the plug-in connector ordinarily employed between a laptop and a docking station may be of a low-voltage, spike voltage protected form, whereby the coupling used for computer logic and control levels is compatible. The possibility of damage to computer circuits due to the proximity of high-voltage telephone line connections is thus avoided.

Abstract: A modem in the form of a single integrated portable unit is provided for operably connecting to a computer for transferring data between the computer and a remote data transfer device over a selected one of a plurality of telephone network access devices including a radiotelephone network access device. The modem includes internal data lines for carrying the data passing between the modem and the radiotelephone network access device, internal control signal lines for carrying control signals for controlling and/or monitoring the operation of the radiotelephone network access device. A jack is connected to the control signal lines and the data lines for providing an external connection of the data lines and signal lines to the radiotelephone network access device. A modem controller operates to access one of a plurality of software drivers for operating the modem in conjunction with the selected one of the plurality of telephone network access devices to cause the operation of the control signal lines to be varied in response to the software driver to permit the control of call placement functions of the selected telephone network access device by the modem.
