[mythtv-users] Unable to control a DCT700 cable box

[Douglas Hitchcock]

This is a dupe from the lirc list, but I'm desperate here!

My mythtv computer has been out of service for almost 3 weeks now, and I
just have no other trouble shooting ideas, I'm completely stuck.  All the
searching I've done, I only seem to find people having problems with the 0
key.  I am having problems with every key.

I bought a dual headed serial IR blaster from irblaster.info.  I'm just
trying to get one box working before I try tackling two.

I am using mythbuntu.  I followed these documents

https://help.ubuntu.com/community/InstallLirc/Gutsy
https://help.ubuntu.com/community/Motorola_DCT700_Channel_Change_Script

My lirc_serial module is loaded, lircd is running, and when I try and

irsend SEND_ONCE DCT700 info

or power, or numbers, or any key at all, with the irsend command or the perl
or python change channel scripts, I get no errors, but the box does not
respond.  I have both blasters taped right above the eye, and I've
repositioned them a thousand times.  I've tried it on two seperate DCT700
boxes.  I did the camera trick where I watch the blasters when I send an
irsend command, and I saw the purple light.  So the blasters work, something
is sending, but it's not have any effect.

I live in Chicago and have RCN cable.  Usually these DCT700 howtos are
associated with Comcast.  Could the boxes be different?  They don't look
special.  I really am out of ideas and pleading for new ideas to try.

here are my config files:
