Abstract
A method and apparatus for isolating communications ports that allows access to a communications system for status and/or maintenance purposes via one communications port while preventing access to same system via the other remaining communications ports are disclosed. The isolation is achieved by an active isolation circuit that precludes a communication with the communication system as long as a signal generated by that communication system indicates that the port should be actively isolated. One preferred embodiment uses the Data Terminal Ready (DTR) signal as an input to the active isolation circuit to actively isolate the selected communication ports. This abstract is provided as a tool for those searching for relevant disclosures, and not as a limitation on the scope of the claims.
