<h2>NAME</h2>
<p>
<b>irpipe</b> - tool to send data to lircd over /dev/irpipe kernel device.
<a name="lbAC"> </a>
</p>
<h2>SYNOPSIS</h2>
<p>
<b>irpipe</b> [<i>options</i>] <file
</p>
<p>
<b>irpipe</b> --read [<i>options</i>] >file
</p>
<p>
<b>irpipe</b> --filter [<i>options</i>] <infile >outfile
</p>
<p>
<a name="lbAD"> </a>
</p>
<h2>DESCRIPTION</h2>
<p>
irpipe is designed to feed data to <a href="lircd.html">lircd</a>(8) over a /dev/irpipe device. It's a tool
to enter test data to lircd in a way which is identical to real data from /dev/lirc
devices.
</p>
<p>
irpipe uses two formats: text and binary. The binary format is documented in
the <a href="mode2.html">mode2</a>(1).
</p>
<p>
The irpipe driver allows user to set the features returned by the
<b>LIRC_GET_FEATURES</b>
ioctl. These are documented in <a href="lirc.html">lirc</a>(4).
</p>
<p>
The irpipe kernel device is often not built in packaged lirc versions. See
[KERNEL DRIVER] below.

<h2>OPTIONS</h2>
<dl>
<div><dt>
<b>-d</b> <b>--device=driver</b>
</dt></div>
<dd>
Set kernel device, default is /dev/irpipe0.
</dd>
<div><dt>
<b>-b</b> <b>--bin2text</b>
</dt></div>
<dd>
Convert binary data to text.
</dd>
<div><dt>
<b>-t</b> <b>--text2bin</b>
</dt></div>
<dd>
Convert text data to binary.
</dd>
<div><dt>
<b>-s</b> <b>--add-sync</b>
</dt></div>
<dd>
Add long initial sync on converted output. This is often required for lircd to
be able to decode data, in particular if keys are not repeated.
</dd>
<div><dt>
<b>-f</b> <b>--filter</b>
</dt></div>
<dd>
Send data from stdin to stdout
</dd>
<div><dt>
<b>-r</b> <b>--read</b>
</dt></div>
<dd>
Send data from kernel device to stdout. This option is experimental and not
tested.
</dd>
<div><dt>
<b>-l--length</b>=<i>bits</i>
</dt></div>
<dd>
Set kernel device signal length. This is only meaningful on LIRCCODE device
emulation.
</dd>
<div><dt>
<b>-F--features</b>=<i>bitmask</i>
</dt></div>
<dd>
Set the features bitmask, as returned by the
<b>LIRC_GET_FEATURES</b>
ioctl. See <a href="lirc.html">lirc</a>(4) for more.
</dd>
<div><dt>
<b>-h</b> <b>--help</b>
</dt></div>
<dd>
Display usage summary.

<h2>KERNEL DRIVER</h2>
<p>
The irpipe tool is designed to work with the irpipe kernel driver, although
the --filter option works without it. This driver is often not built
in packaged versions. If this is the case, the driver can be built from
sources in the drivers/irpipe directory. This requires kernel sources
installed. The drivers/irpipe/README provides information on building
and installing the driver.
