I had a lot of trouble changing channels reliably since I moved to dish network 301 receivers from a 5xx series. Someone suggested that the gap value in the file may have to be changed and that it was cpu/serial port dependent.
I kept changing it and figured it was a lost cause at one point, and was about to order a MyBlaster, but then I decided to change it some more and eventually ended up with something that seems ok. I started with a gap of 175000 and ended with 400000 in /etc/ledxmitd.conf. I tossed together this script to zap and restore things to try different gap values. I'm sure someone could clean it up if they cared to do so... #!/bin/bash modprobe -r ledxmit_serial modprobe -r ledxmit_dev PID=$(ps -A | grep ledxm | egrep -o "[0-9]{3,5}") echo "Found PID=[$PID]" if [[ "$PID" != "" ]] then echo "Killing existing instance of ledxmit..." kill -s 9 $PID fi /bin/echo "Starting ledxmit stuff..." setserial /dev/ttyS0 uart none update-modules modprobe ledxmit_serial nice -n -20 /usr/local/lirc-ledxmit/sbin/ledxmit-ledxmitd ---- For reference that is an AMD XP 2000+ (Technically it is actually an AMD MP 1900+ running as a 2000+.) with an nforce 2 motherboard. It seems that the normal way of entering remote codes from an unknown remote will determine the value of the gap, but, unfortunately, dish network receivers run at 56kHz(?) and my IR receiver doesn't pick up them, so I was stuck working from a premade file and guessing. -Robert On Wed, 2005-10-26 at 13:19 -0400, George Nassas wrote: > On 26-Oct-05, at 1:08 PM, Scott S. wrote: > > > Has anyone seen this?
