I had a working FC5 MythTV system on my upstairs computer with a home-brew serial port receiver. I wanted to move it to my downstairs FC5 system, so I installed lirc from rpms. I've loaded the lirc_serial module, but nothing seems to respond. mode2 doesn't give any output, I took the receiver back upstairs to check the receiver still works - it did.

So on the downstairs computer, I have:
[root@localhost ~]# rpm -qa | grep -i lirc

dmesg reports:
[root@localhost ~]# dmesg | grep -i lirc
lirc_dev: no version for "struct_module" found: kernel tainted.
lirc_dev: IR Remote Control driver registered, at major 61
lirc_serial: auto-detected active high receiver
lirc_dev: lirc_register_plugin: sample_rate: 0

Following the instructions from http://wilsonet.com/mythtv/fcmyth.php#lirc I have in my modprobe.conf:

alias char-major-61 lirc_serial
options lirc_serial irq=4 io=0x3f8
install lirc_serial /bin/setserial /dev/ttyS0 uart none; /sbin/modprobe --ignore
-install lirc_serial

and in /etc/sysconfig/modules/lirc.modules I have:


for module in `/sbin/modprobe -c | awk '/^alias[[:space:]]+char-major-61+[[:spac
e:]]/ { print $3 }'`; do
        /sbin/modprobe $module

When I do modprobe lirc_serial I get
lrwxrwxrwx 1 root root     5 Oct 29 14:59 /dev/lirc -> lirc0
crw------- 1 root root 61, 0 Oct 29 14:59 /dev/lirc0

But I still get nothing from mode2 or irrecord. I've never used the COM port on this motherboard before, is there anyway I can tell if the COM port is working properly? What driver should I use as an option for irrecord, I thought there was a --driver=serial option, but it says "not supported"?
