Abstract: Improved transmission speed of data between computer systems is achieved by utilizing highest priority interrupts assigned to non-communication devices to control communications. In particular, the normally highest priority timer interrupts are used to poll communication buffers to determine whether data needs to be sent or received with such polling replacing the use of the interrupts typically associated with communication devices.

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.
