Abstract
A system and method for the provision of communication across multiple devices in a multiplicity of communication environments, whether in a serial interface environment, or whether used in Bluetooth protocol-based devices, as well as in other communication devices, (ZigBee/WiFi/Wimax, etc.) that normally cannot readily establish such data exchange. The invention accomplishes this through inventive techniques and a circuit that uses multi-state voltage levels to multiplex RS232 communication between at least two, but normally three or more RS232 devices. To this end, the present invention enables a device having RS232 connection between at least two sub-systems, while each sub-system communicates with other external RS232 devices using same RS232 connection between at least two sub-systems.
