irrecord: could not open =/dev/lircd

[skchae <sk...@as...>]

I use redhat80.

Mode2 works very well so I can see signal on monitor.

But irrecord does not work and emit error message. "irrecord : could not open 
=/dev/lircd"

I changed  /dev/lircd's permissinon by 666.

The result of lsmod is below
----------
Module                  Size  Used by    Tainted: PF
lirc_serial             9088   0

What's problem?
