I don't know if it'll help, but I've written 16C84 code to receive and decode
the IR signals from Sharp Electronics remote controls. All the recent ones
are based on the same coding system and have a different 'system code' for
TV, VCR and Audio. My code allows the switching on and off of various of the
PortB pins, the keys used are held in a lookup table.
