Patent ID: 8295368

Claim:
A system for the provision of communication across multiple Data terminal Equipment (DTE)/Data Circuit-terminating Equipment (DCE) serial devices in a multiplicity of communication environments comprising: a multi-state switching circuit, wherein said multi-state switching circuit is situated proximate to a group of DTE/DCE devices, said multi-state switching circuit including an electrical connection for connecting to any of at least two DTE/DCE devices to each other within said group of DTE/DCE devices via each respective port of said at least two DTE/DCE devices, said multi-state switching circuit having a voltage logic which employs only one signal with multiple different voltage levels set according a total number of said multiple DTE/DCE devices; and said multi-state switching circuit having predetermined switch settings equal to said total number of said multiple DTE/DCE devices for an establishment of a communication route between said at least two DTE/DCE devices.
