Chapter 4 / Infrared Communications Overview
miniport driver must calculate CRC. For VFIR link speeds, a 32-bit
CRC is used, which is the same as that used for FIR link speeds. An
algorithm for calculating the 32-bit CRC is available in the publication
Infrared Data Association Serial Infrared Physical Layer Link
Specification.
The IrDA specification will give you an idea of the technical details
involved in the protocol. When we write to the software, you will find
it is not as complicated as it seems. The creators of the Windows and
Palm operating systems gave an application programming interface
(API) that makes creating an association, sending, and receiving data
a fairly straightforward task.
