Abstract

A system (102) comprises a portable computer (104) with a central processing unit (106) and associated software (108) and a modem (110) with an output jack (112) carrying data transmit (128), data receive (126) tip, ring (134), and programmable digital input/output (130) lines sufficient to facilitate control of a large number of alternative telephone access devices (116). The operation and functions of the tip, ring, TX, RX and programmable DIO lines are controlled in a preferred embodiment by software in the modem (110) under the control of the software in the computer (104). In a preferred embodiment, a user operates the software in the computer (104) to specify a type or model of telephone access device (116) being used with the modem (110) and the RX, TX, tip and ring lines are rendered either operable or inoperable and a required subset of the programmable DIO lines are caused to operate in a manner necessary to achieve interactive control of an attached telephone access device (116).
