hi ... on a laptop, simple transmitter as per http://lirc.org/transmitters.html works with winlirc-0.6.5, but not on a desktop with  lirc-0.7.1  on mandriva 2006.0 (Official);

if anyone could suggest what to do, it would be most appreciated...thanks!!!

 here are details:

# cp -p /usr/share/lirc-remotes/motorola/IRC442 /etc/lircd.conf

# grep '^[^ #]'  /etc/sysconfig/lircd
DRIVER=default
HWMOD=lirc_serial
DEVICE=/dev/lirc/0
COM_PORT=/dev/ttyS0
DRIVER_OPTS="irq=4 io=0x3f8"

# setserial /dev/ttyS0 uart none

# modprobe lirc_serial irq=4 io=0x3f8 debug=1

# /etc/init.d/lircd start

==> syslog <==
lirc_dev: IR Remote Control driver registered, at major 61
lirc_serial: in init_timing_params, freq=38000, duty_cycle=50, clk/jiffy=7213705,  pulse=23729, space=23729, conv_us_to_clocks=1803

 # cat /proc/tty/driver/serial

2: uart:unknown port:000003E8 irq:4
3: uart:unknown port:000002E8 irq:3

 an oscilloscope shows that from remote regular signal kind of like this:
~~~~~~~~~|_|~|_|~|_|~|_|_|_|~~|_|_|~~|_|~~~~~~~~~~
but from the lirc-0.7.1 it only shows:
~~~~~~~~~|_____________________________|~~~~~~~~~~

so timing is right, but the DTR line doesn't fluctuate
up and down like it should to send the signal.

from lirc.spec:
%build
%configure2_5x --localstatedir=/var \
--with-x \
--with-port=0x3f8 \
--with-irq=4 \
--disable-manage-devices \
--with-syslog=LOG_DAEMON \
--with-driver=any \
--with-transmitter

kernel-2.6.16.1mdk-1-1.mdk2006.0.mde

then when # irsend SEND_START CH_UP
produces six to nine duplicates of these two lines:
==> syslog <==
lirc_serial: SET_SEND_DUTY_CYCLE
lirc_serial: in init_timing_params, freq=38000, duty_cycle=50, clk/jiffy=7213705, pulse=23729, space=23729, conv_us_to_clocks=1803
and after a minute it ends with:
lirc_serial: freed IRQ 4
