Abstract

A data processing method includes, at an external computer, originating a ready control signal and, at a host, receiving the ready control signal. In response to the ready control signal, a control signal is produced by the host. In response to the control signal, a switch selectively couples one of the host and the first computer to a telecommunication device.

Claims (17)

1. A data processing apparatus configured for operation in conjunction with an external computer, the external computer selectively originating a ready control signal, the data processing apparatus comprising:

a host configured to receive the ready control signal and produce a control signal in response thereto;

a telecommunication device;

a switch circuit which selectively couples one of the host and the external computer to the telecommunication device in response to the control signal from the host; and

a first switch to couple one of a data output of the external computer and an output of the host with an input of the telecommunication device; and

a second switch to couple one of an output of the host and an output of the telecommunication device with an input of the external computer.

2. The data processing system of claim 1 wherein the host is configured to:

generate the control signal for coupling the external computer to the telecommunication device in response to receipt of the ready control signal; and

generate the control signal for coupling the host to the telecommunication device in response to absence of the ready control signal.

3. The data processing system of claim 1 further comprising:

a connector to detachably couple the external computer and the switch circuit.

4. The data processing system of claim 1 further comprising:

a first host serial communication circuit to couple the host with the switch circuit and the external computer; and

a second host serial communication circuit to couple the host with the switch circuit and the telecommunication device.

5. The data processing system of claim 1 wherein the telecommunication device comprises a radiotelephone.

6. The data processing system of claim 1 wherein the telecommunication device comprises a cellular telephone.

7. The data processing system of claim 5 wherein the telecommunication device comprises a satellite telephone.
