UPDATE 22/2/15: OK apparently the reason for the mess is that lirc_serial needs to be compiled/provided/supported by the kernel and is not included in recent lirc versions.
ELREPO has kmod-lirc for Centos that seems to work out of the box (manually load it after "
setserial /dev/ttyS? uart none" for el7 too). So you can install lirc using yum.
I needed to turn on the AC unit in a small server room. It would go off when a power failure occurred.
I purchased a
serial transceiver from Iguana works.
Since Centos' (2.6.18-274.7.1.el5) lirc package did not include the default driver and lirc_serial modules, I downloaded
lirc-0.8.7 (lirc-0.9.0 would not compile).
Compilation is pretty straight forward:
./setup.sh
make
make install
During setup I chose the serial port the transceiver was on.
Next steps are:
Copy the init script from contrib and adjust it to your requirements. Do not start lirc though.
Here is my init script:
#!/bin/sh
#
# lirc: This is an init script for RedHat distribution.
#
# Author: Denis V. Dmitrienko
#
# chkconfig: 345 95 10

status lircmd
;;
restart)
$0 stop
$0 start
;;
*)
echo "Usage: lirc {start|stop|status|restart}"
exit 1
esac
exit 0
Create /etc/sysconfig/lirc file:
# Arguments which will be used when launching lircd
LIRCD_ARGS=""
# Run "lircd --driver=help" for a list of supported drivers.
DRIVER="default"
# Check which the name when lirc_serial is loaded
DEVICE="/dev/lirc0"
# lirc_dev will be loaded automatically
MODULES="lirc_serial"
#the serial port of your device
PORT="/dev/ttyS1"
Try to start lirc now.
Make sure that lirc_serial is loaded i.e. lsmod | grep lirc should produce something similar to:
lirc_serial 16980 1
lirc_dev 17176 3 lirc_serial
AC remote signals are more like complete status updates than state relative commands. irrecord will not work with that. Use
mode2 -m and for each remote command capture the output in a file. Lircd must be stopped in order for mode2 to work Remove any blank lines and the first line if it only contains one number (leave any 6 columns of numbers). Repeat the process for any other states you wish. Capturing under fluorescent light can cause errors so turn off the lights for better results. When you use mode2 lirc should not be running.
Create the /etc/lirc/lircd.conf file and add the data from the previous step inside the raw_codes section. Precede each data block with a name line as shown below.

The gap value can be any number similar to what I've used, it does not matter since it doesn't apply for AC remotes. If it
's too big it will block irsend for a significant amount of time though.
Next step is to try and start lirc. If all goes well you should be able to try sending commands using:
irsend DIRECTIVE REMOTE_NAME CODE_NAME
for instance:
irsend SEND_ONCE AC ON_24
