Two computers are serially connected by a one-way cable connection allowing data to be transmitted from the first computer to the second computer, but making it physically impossible to transmit data from the second computer to the first computer. A serial port of the first computer has a transmitting pin in hard-wired communication with a receiving pin of a serial port of the second computer. The grounding pins of the respective serial ports of the first and second computers are hard-wired connected. The invention uses a two-conductor BNC coaxial connection cable and connecting adapters.
