Method, apparatus and system for changing to which remote device a local device is in communication via a communication medium through use of interruption of the communication medium

A communication system, comprising:

• a keyboard, video, mouse, (KVM), local device;
• and
• an input/output (I/O) device;
• wherein the KVM local device is configured to be toggled between a first state and a second state so as to generate a toggling pattern, the KVM local device being configured to be maintained in the first state during a first duration, and to be maintained in the second state during a second duration that matches the first duration;
• wherein the I/O device is configured to detect the toggling pattern generated in response to the KVM local device being toggled between the first state and the second state;
• wherein the I/O device is configured to facilitate secure switching of communications from between the KVM local device and a first remote device to between the KVM local device and a second remote device based on the detected toggling pattern.
