1.2. 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.

For 2.0.x kernels Linux/IrDA support worked in a totally other way (only user-land programs) and is no longer supported by the Linux/IrDA project. Since 2.1.131 and 2.2.0 it is part of the kernel.

• the major device number of the irda device changed from 61 to 161 (as far as I remember there was also a major number 60 around, too), also there have been different and now obsolete minor device numbers around, see the list of current device numbers below

• the irmanager is obsolete now, its tasks are now achieved by irattach

• the module name /dev/ircomm_tty changed to /dev/ircomm-tty , but there are other modules around which use either "-" or "_" in there names, this might be confusing

• the device names /dev/irnine and /dev/ircomm_new are obsolete

• IrLPT is handled by IrCOMM now. So all references to irlpt_server are obsolete.

• From irda-utils 0.9.15 the behaviour of the -s option of irattach has changed. The option must not use the parameter 1 anymore.
