ABSTRACT:
A system and method is provided by the present invention for transmitting or receiving data to or from a computer system by reprogramming the computer system's clock. The invention provides an executive processor which interfaces to an operating system and initiates a reprogramming of the clock upon an occurrence of a predetermined condition. The reprogramming of the system clock includes a method for determining a resolution constant which is used to generate a clock counter value. The method of determining the resolution constant includes methods of determining CPU interrupt latency CPU index speed, computer system UART baud rate.
