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.
