2. Code History

The Linux/IrDA project has undertaken some changes in the program code, which you should know to understand some possible confusions with older documentation, which you shouldn't use anyway.


Some caveats in the documentation have been caused by changes of the following concepts, device names and parameters. I hope I have got them alright now, they confused me sometimes, too. The new style stuff works from Kernel 2.2.15 / 2.4.0. Some important changes were made again in Kernel 2.6, not all of these are mentioned in this document yet, I will fix that hopefully soon. Anyway I recommend not to use any earlier kernel version than 2.6. This document will describe differences to the kernel 2.4 series in the appropriate places to provide documentation for situations where you must use kernel 2.4, which is hopefully rare. You should always use current Kernel, irda-utils and documentation.
