[mythtv-users] mythdora lirc problems, remote+serial blaster

I'm running Mythdora 12.23 with a Hauppauge 250 and am having trouble with
both the Hauppauge remote and a serial blaster. The reciever is the one
that plugs into the back of the Hauppauge card and the blaster is a
homebuilt LED+resistor+diode from the Lirc page.
When I first installed the system, and used the Mythdora IR devices
configuration tool to set up just the remote, it worked fine. Later when I
used the configuration tool to add the blaster, the remote stopped working
and the blaster never worked. I chose the option that said
"serial/IguannaWorks IR Blaster(COM1)". Since I didn't make any manual
changes outside of the config tool I'm assuming that the tool messed up
the settings.
I've followed the various troubleshooting sources that I can find, but
many of them are old or are for MythBuntu, which seems to have a different
configuration. I'm hoping someone can see the problem from what I've
posted here or can walk me through the correct troubleshooting steps.
I know the light is flashing on the Hauppauge remote but I can't get any
output from irw. When I add the channel change script to Myth I get error
messages in the backend log that say:
irsend: command failed: SEND_ONCE Pace_RC-30 6
irsend: hardware does not support sending
irsend: command failed: SEND_ONCE Pace_RC-30 6
irsend: hardware does not support sending
irsend: command failed: SEND_ONCE Pace_RC-30 OK
irsend: hardware does not support sending
Note that my remote is actually the Pace DC50X but that's not listed in
the configuration tool. I figured I would worry about the actual remote
type later after I got the blaster light to flash.
Here are the results of some of the troubleshooting commands I have found.
Let me know what other info I can provide.
