Abstract:
1. A data transfer system, comprising: a modified USB cable including: (a) a power line, (b) a first data line, (c) a second data line, and (d) a control line to control a USB reception thread; a terminal for transmitting a control signal through the control line for initiating data transmission through at least one of the first data line or the second data line; and a computer including a circuit to generate an interrupt signal in response to the control signal received through the control line, the computer executing a USB reception thread for processing data transmitted from the terminal through the first or second data lines of the cable in response to the interrupt signal, wherein the interrupt signal causes control of execution of one or more other threads in the computer to be interrupted and causes a program of the computer to execute the USB reception thread, wherein the interrupt signal is generated only at a time when the control signal is received through the control line from the terminal.
