    • A system and storage medium for providing continuous communication between passive and active equipment are provided. The system includes a conversion unit coupled to at least one the passive and active equipment, which monitors signals received from the equipment. The signals relate to an equipment state. Upon detecting a state change, the system converts a signal associated with the state change to a TCP/IP-formatted request. The system also includes a message handler coupled to the conversion unit, which receives the request from the conversion unit and transmits the request to a host system. The message handler also removes TCP/IP formatting from the request resulting in a file transfer protocol message. The conversion unit converts the file transfer protocol message to a signal and responds to the signal by the equipment. The conversion includes decoding the file transfer protocol message and setting a signal line to a requested state.
