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 <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.

Say Y here to support the connectionless Ultra IRDA protocol.
|
||
|
|
Ultra allows to exchange data over IrDA with really simple devices
|
||
|
|
(watch, beacon) without the overhead of the IrDA protocol (no handshaking,
|
||
|
|
no management frames, simple fixed header).
|
||
|
|
Ultra is available as a special socket : socket(AF_IRDA, SOCK_DGRAM, 1);

help
|
||
|
|
Say Y here if you want IrLMP to cache the last LSAP used. This
|
||
|
|
makes sense since most frames will be sent/received on the same
|
||
|
|
connection. Enabling this option will save a hash-lookup per frame.
|
||
|
|
|
||
|
|
If unsure, say Y.

depends on IRDA
|

|
---help---
|
||
|
|
Say Y here is you want IrLAP to send fast RR (Receive Ready) frames
|
||
|
|
when acting as a primary station.
|
||
|
|
Disabling this option will make latency over IrDA very bad. Enabling
|
||
|
|
this option will make the IrDA stack send more packet than strictly
|
||
|
|
necessary, thus reduce your battery life (but not that much).
|
||
|
|
|
||
|
|
Fast RR will make IrLAP send out a RR frame immediately when
|
||
|
|
receiving a frame if its own transmit queue is currently empty. This
|
||
|
|
will give a lot of speed improvement when receiving much data since
|
||
|
|
the secondary station will not have to wait the max. turn around
|
||
|
|
time (usually 500ms) before it is allowed to transmit the next time.
|
||
|
|
If the transmit queue of the secondary is also empty, the primary will
|
||
|
|
start backing-off before sending another RR frame, waiting longer
|
||
|
|
each time until the back-off reaches the max. turn around time.
|
||
|
|
This back-off increase in controlled via
|
||
|
|
/proc/sys/net/irda/fast_poll_increase
|
||
|
|
|
||
|
|
If unsure, say Y.

|
help
|
||
|
|
Say Y here if you want the IrDA subsystem to write debug information
|
||
|
|
to your syslog. You can change the debug level in
|
||
|
|
/proc/sys/net/irda/debug .
|
||
|
|
When this option is enabled, the IrDA also perform many extra internal
|
||
|
|
verifications which will usually prevent the kernel to crash in case of
|
||
|
|
bugs.
|
||
|
|
|
||
|
|
If unsure, say Y (since it makes it easier to find the bugs).
