Abstract
Disclosed is an improved hardware approach for increasing the efficiency of infrared asynchrounous communication performance. By utilizing the Infrared Data Association's Serial Infrared Link Access Protocol (IRLAP) along with hardware assist, and DMA associated with most microprocessors, e.g. conventional PC's, the processor is free to carry out other functions without having to process the IR communications for both transmit and receive.
