[mythtv-users] HELP: I messed up my IR Blaster config, now it doesn't work

I'm running a Gentoo-based MythTV system with a DISH satellite receiver
that was been working fine for many months. But I couldn't leave it well
enough alone, and in the process of fixing something that probably
wasn't even broke to begin with (and that I can no loner even remember)
I broke my IR Blaster config.
Details:
Gentoo running kernel 2.6.13-gentoo-r5
Running udev
IR blaster from http://www.irblaster.info
Lirc config to drive it based on the instructions at
http://losdos.dyndns.org:8080/public/mythtv-info/MythTV_DISH_IR_LED_TX_via_Modified_LIRC.html
JVC_RAW command set in /etc/ledxmit.conf
Module options look like this:
alias char-major-72 ledxmit_serial
below ledxmit_serial ledxmit_dev
pre-install ledxmit_serial /bin/setserial /dev/ttyS0 uart none
options ledxmit_serial irq=4 io=0x3f8
I have been using lirc 0.72 to build the ledxmit stuff, and now I'm
trying 0.8.0. I'd be happy getting either to work.
Everything makes and installs fine, but I run into the following problems:
1. It seems to want /dev/ledxmit, but I only have /dev/ledxmitd and
/dev/ledxmit0 (which is the 72,0 device). I suppose this is because I'm
running udev. Fine, I made a symlink called 'ledxmit' that points to
ledxmit0 and that problem goes away. Is that correct? I end up with this:
lrwxrwxrwx 1 root root 8 Mar 6 08:11 ledxmit -> ledxmit0
crw-rw---- 1 root root 72, 0 Mar 6 08:10 ledxmit0
srw-rw-rw- 1 root root 0 Mar 6 08:09 ledxmitd
2. When I run my channel change script (which calls ledxmit-irsend) I
get the following errors (example is trying to change to channel 3):
Mar 6 07:31:48 mythtv ledxmitd: accepted new client on /dev/ledxmitd
Mar 6 07:31:48 mythtv ledxmitd: too short gap: 100000
Mar 6 07:31:48 mythtv ledxmitd: error processing command:
SEND_ONCE JVC_RAW 3
Mar 6 07:31:48 mythtv ledxmitd: transmission failed
Mar 6 07:31:48 mythtv ledxmitd: removed client
Any ideas on what I might have done to kill it? I've re-installed it
several times and tried several different options, but nothing seems to
make a difference.
