Few other things:
My cable box is a SA3100 , so supposedly operating at 57600 carrier frequency.  Now I have seen the posts that say that won't work , but that carrier freq is defined in lirc_sir.c so that wouldn't make sense. 
Anyway I am trying the file out of the remotes tar Explorer_2000
I sent a change_channel.csh 13
Send 1 was fine, Send 3 was fine, I get an error on Enter, as "Unknown command"
Not sure where to fix that and if it's fixed will it work.

Installed lirc for the actisys 200L.  irw does not seem to be working.  Enabling debug has not shed any light either.
Once I modprobe lir_sir and then /sbin/lircd , log say lircd(act200L) ready
then when I activate irw log say "accepted new client on /dev/lircd"
after irw hangs , I ctrl-c  log say "removed client"
mode2 does work, irrecord has had mixed results.
irrecord will detect an RC-6 then hang forever while it looks for a toggle bit
other times it has created a file for me as a RC-5 , goes through the steps and then the definitions of names  / buttons.
I was under the assumption that irw should be tried first and if nothing , to suspect something is wrong?
I just dont see where the problem could be.
