IrDA Internals

This is a subset of an early version of the book 'IrDA Internals'. Some content has been omitted due to the amount of time / effort & space needed for HTML formatting.

The reader must have the IrDA specifications covering IrLAP, IrLMP, IrTTP and IrCOMM - these documents are in the public domain. Among other things, these specifications cover the frame formats and byte / bit allocations.
