NAME

       irpipe - tool to send data to lircd over /dev/irpipe kernel device.

SYNOPSIS

       irpipe [options] <file

       irpipe --read [options] >file

       irpipe --filter [options] <infile >outfile

DESCRIPTION

       irpipe  is designed to feed data to lircd(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.

       irpipe uses two formats: text and binary. The binary format is documented in the lirc(4) manual page. The
       text format is as defined in mode2(1).

       The irpipe driver allows user  to set the features returned by the  LIRC_GET_FEATURES  ioctl.  These  are
       documented in lirc(4).

       The irpipe kernel device is often not built in packaged lirc versions. See [KERNEL DRIVER] below.

OPTIONS

       -d --device=driver
              Set kernel device, default is /dev/irpipe0.

       -b --bin2text
              Convert binary data to text.

       -t --text2bin
              Convert text data to binary.

       -s --add-sync
              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.

       -f --filter
              Send data from stdin to stdout

       -r --read
              Send data from kernel device to stdout. This option is experimental and not tested.

       -l--length=bits
              Set kernel device signal length. This is only meaningful on LIRCCODE device emulation.

       -F--features=bitmask
              Set the features bitmask, as returned by the LIRC_GET_FEATURES ioctl. See lirc(4) for more.

       -h --help
              Display usage summary.

       -v --version
              Display version.

KERNEL DRIVER

       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.
