This is what I see in the terminal after putting things back:

daryl at daryl-A780L3C:~$ ls /dev/lirc*
/dev/lirc0  /dev/lirc1  /dev/lircd  /dev/lircSerial
daryl at daryl-A780L3C:~$ dmesg | grep lirc
[   26.059015] lirc_dev: IR Remote Control driver registered, major 250
[   26.059485] rc rc0: lirc_dev: driver ir-lirc-codec (cx88xx) registered
at minor = 0
[   27.964481] lirc_serial: module is from the staging directory, the
quality is unknown, you have been warned.
[   28.863438] lirc_serial: auto-detected active high receiver
[   28.863553] lirc_serial lirc_serial.0: lirc_dev: driver lirc_serial
registered at minor = 1
daryl at daryl-A780L3C:~$ /usr/local/bin/check_stb
irsend: command failed: SEND_ONCE DCT700 info
irsend: unknown remote: "DCT700"
daryl at daryl-A780L3C:~$

And this is the /etc/lirc/hardwaqre.conf file:

# /etc/lirc/hardware.conf
#
#Chosen Remote Control
REMOTE="None"
REMOTE_MODULES=""
REMOTE_DRIVER=""
REMOTE_DEVICE=""
REMOTE_SOCKET=""
REMOTE_LIRCD_CONF=""
REMOTE_LIRCD_ARGS=""

#Chosen IR Transmitter
TRANSMITTER="Serial Port (UART) : Motorola Cable box"
TRANSMITTER_MODULES="lirc_dev lirc_serial"
TRANSMITTER_DRIVER=""
TRANSMITTER_DEVICE="/dev/lircSerial"
TRANSMITTER_SOCKET=""
TRANSMITTER_LIRCD_CONF="motorola/dctxxxx.conf"
TRANSMITTER_LIRCD_ARGS=""

#Enable lircd
START_LIRCD="true"

#Don't start lircmd even if there seems to be a good config file
#START_LIRCMD="false"

#Try to load appropriate kernel modules
LOAD_MODULES="true"

# Default configuration files for your hardware if any
LIRCMD_CONF=""

#Forcing noninteractive reconfiguration
#If lirc is to be reconfigured by an external application
#that doesn't have a debconf frontend available, the noninteractive
#frontend can be invoked and set to parse REMOTE and TRANSMITTER
#It will then populate all other variables without any user input
#If you would like to configure lirc via standard methods, be sure
#to leave this set to "false"
FORCE_NONINTERACTIVE_RECONFIGURATION="false"
START_LIRCMD=""

Not fair, this should have worked.    Daryl
