[mythtv-users] lirc woes (no output from mode2)

[matt lutz]

All,

I'm hoping someone can point me in the right direction.  I have a serial
receiver that I'm trying to get working with myth.

It does work on one of my systems with an identical setup, so I don't think
the problem lies with lirc, lirc_serial, or the receiver itself.  The
problem is, I don't see errors anywhere, it just doesn't work.  I'm running
FC6 with kernel 2.6.20-1.2948.fc6.

Here are the relevant log entries:

[root at localhost ~]# dmesg | grep ttyS
serial8250: ttyS0 at I/O 0x3f8 (irq = 4) is a NS16550A
00:09: ttyS0 at I/O 0x3f8 (irq = 4) is a NS16550A

[root at localhost ~]#cat /var/log/messages | grep lirc
May 15 20:05:15 localhost kernel: lirc_dev: no version for "struct_module"
found: kernel tainted.
May 15 20:05:15 localhost kernel: lirc_dev: IR Remote Control driver
registered, at major 61
May 15 20:05:15 localhost kernel: lirc_serial: auto-detected active low
receiver
May 15 20:05:15 localhost kernel: lirc_dev: lirc_register_plugin:
sample_rate: 0
May 15 21:19:40 localhost lircd-0.8.2-CVS[3756]: you should specify a valid
gap value
May 15 21:19:40 localhost lircd-0.8.2-CVS[3756]: lircd(userspace) ready
May 15 21:36:04 localhost lircd-0.8.2-CVS[3756]: caught signal


All of which is almost exactly the same as the working setups.  And yet
mode2 shows nothing on the receiver.  I even went as far as to load XP on
this machine and used WinLirc, which was fine.  Only weird thing was that I
had to use COM2, but with the same IRQ I/O settings.  I assumed that was
because of a built-in modem or something, but maybe it's screwing with
linux?

The only other oddity is that on my working system , the dmesg | grep ttyS
shows the following:

00:0a: ttyS0 at I/0 0x3f8 (irq=4) is a NS16550A

A bit different, but still nothing that would indicate an error.  Any
suggestions on what I can do to troubleshoot?

thanks,
matt
