An apparatus and method for providing infrared (IR) signaling, comprising a processor coupled to a memory, for generating a symbol sequence. A modulator then converts each symbol in said symbol sequence into a 5 pulse position modulated (5PPM) signal. The symbol sequence represents an IR signaling protocol having a payload portion and a header portion, wherein the header portion comprises a plurality of fields for defining the payload portion. The payload portion indicates keyboard characters or coordinates for a pointing device.
