REMOTE_NAME=DCT2524
for digit in $(echo $1 | sed -e 's/./& /g'); do
irsend --device=/dev/lircd SEND_ONCE $REMOTE_NAME $digit
sleep 0.4 # note, you may have to tweak the interdigit delay up a bit
done
irsend --device=/dev/lircd SEND_ONCE $REMOTE_NAME ok/select

So I would change these items:

irsend --device=/dev/irblasterd to irsend --device=/dev/lircd

and then it would know to look in the lircd.conf file for the needed REMOTE_NAME

And all i would have to do is change the /dev and copy my irblasterd.conf file for the dish 301 receiver into the lircd.conf file

Am I correct?
