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 method of communicating, comprising:

• toggling a transmitter On and Off in a pattern of interruption to generate multiple consecutive On/Off bits having On/Off signals with a same pulse width that represents control information, the transmitter configured to transmit data via a communication medium;
• interrupting the communication medium corresponding to the pattern of interruption so as to detect a loss of signal on the communication medium;
• using the detected loss of signal to detect the pattern of interruption of the communication medium to determine the control information;
• changing to which remote device of a plurality of remote devices the local device is in communication with via the communication medium based on the detected loss of signal that detects the pattern of interruption and the determined control information;
• and
• wherein the local device comprises a secure data communications device that is configured to change from which remote device of the plurality of remote devices the local device is in communication via the communication medium without inserting a control command into the communication medium, and without using a communication path separate of the communication medium for the pattern of interruption between the local device and the remote device that the local device is in communication with.

A method for securely switching a KVM local device from a first remote device to a second remote device comprising:

• toggling the KVM local device between a first state and a second state so as to generate a toggling pattern, where the KVM local device is maintained in the first state during a first duration, and the KVM local device is maintained in the second state during a second duration that matches the first duration;
• detecting the toggling pattern generated in response to the KVM local device being toggled between the first state and the second state;
