ABSTRACT:
A system including a portable computer with a central processing unit and associated software, and a modem with an output jack carrying data transmit (TX), data receive (RX), tip, ring, and programmable digital input/output (DIO) lines sufficient to facilitate control of a large number of alternative telephone access devices. 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 under the control of the software in the computer. In a preferred embodiment, a user operates the software in the computer to specify a type or model of telephone access device being used with the modem, 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.
