Say Y here if you want to build support for the IrDA (TM) protocols.
The Infrared Data Associations (tm) specifies standards for wireless
infrared communication and is supported by most laptops and PDA's.

To use Linux support for the IrDA (tm) protocols, you will also need
some user-space utilities like irattach. For more information, see
the file Documentation/networking/irda.txt. You also want to
read the IR-HOWTO, available at
<http://www.tldp.org/docs.html#howto>.

If you want to exchange bits of data (vCal, vCard) with a PDA, you
will need to install some OBEX application, such as OpenObex :
<http://sourceforge.net/projects/openobex/>

To compile this support as a module, choose M here: the module will
be called irda.
