Product: lirc
Component: documentation
Summary: lirc not correctly creating symlinks for serial devices
Version: 0.6.6-1mdk
Platform: PC
OS/Version: All
Status: UNCONFIRMED
Severity: normal
Priority: P2
AssignedTo: [EMAIL PROTECTED]
ReportedBy: [EMAIL PROTECTED]
I have a pinnacle systems "dumb" IR receiver which connects to the COM1 / COM2 serial
port.
The example /etc/sysconfig/lircd file gives the user no indication that they need to
create a
symlink between the actual tty device and the /dev/lirc entry.
Here's a working example:
# Customized setings for lirc daemon
# The hardware driver to use, run lircd --driver=? for a list
DRIVER=pinsys
# Hardware driver module to load
HWMOD=serial
# The device node that communicates with the IR device.
# with devfs enabled
DEVICE=/dev/lirc/1
<snip>
[EMAIL PROTECTED] dev]# ls -l /dev/lirc/1
lr-xr-xr-x 1 root root 10 Mar 15 21:48 /dev/lirc/1 -> /dev/ttyS1
It took me about 2 hours to figure this out. I recommend that the lircd file be a
little more
verbose with examples.
Here is an updated /etc/sysconfig/lircd file that I think explains things better.
(Note that the symlink is created correctly when manually installing lirc from a
tarball because
the lirc configure program does this as a part of the installation process)
[EMAIL PROTECTED] sysconfig]# cat lircd
# Customized setings for lirc daemon
# The hardware driver to use, run lircd --driver=? for a list
DRIVER=UNCONFIGURED
# Hardware driver module to load
# Choices are:
# serial
# lirc_serial (for home-brew serial port IR receivers)
# lirc_parallel
# etc. See /lib/modules/{kern-version}/kernel/3rdparty/lirc for a
# list of modules.
HWMOD=UNCONFIGURED
# The device node that communicates with the IR device.
# If you are using a serial device, create a symlink between the actual
# hardware device and the /dev/lirc/ entry
# Example for receiver connected to COM1
# <as root># cd /dev
# <as root># ln -sf ttyS0 lirc/0
# or <as root># ln -sf ttyS0 lirc/serial
# If you are using devfs, use one of the following and create the symlink
# as shown above
# DEVICE=/dev/lirc/0
# DEVICE=/dev/lirc/serial
# Without devfs:
# If you are using a serial device, create a symlink between the actual
# hardware device and the /dev/lirc entry
# Example for receiver connected to COM1
# <as root># cd /dev
# <as root># ln -sf ttyS0 lirc
# DEVICE=/dev/lirc
# Serial port for the receiver (for serial driver)
# COM1 (/dev/ttyS0)
#COM_PORT=/dev/ttyS0
#DRIVER_OPTS="irq=4 io=0x3f8"
# COM2 (/dev/ttyS1)
#COM_PORT=/dev/ttyS1
#DRIVER_OPTS="irq=3 io=0x2f8"
# COM3 (/dev/ttyS2)
#COM_PORT=/dev/ttyS2
#DRIVER_OPTS="irq=4 io=0x3e8
# COM4 (/dev/ttyS3)
#COM_PORT=/dev/ttyS3
#DRIVER_OPTS="irq=3 io=0x2e8"
