I've tried both ports.  I've also tried another IR emitter (the
dual-ended one that came with my Tivo years ago), and it doesn't work

irsend SET_TRANSMITTERS 1 and SET_TRANSMITTERS 2 both run without
generating any error messages.  Any other number (0,3,4 ,etc) and it
will complain.

My lircd.conf is pretty simple.  I downloaded the config for the
Motorola VIP 1200 box from lirc.org, and that's the only remote
defined in it.  The only change I've made is to replace the words like
"ONE" for the numeral "1".  Like I said, I can fire up irw, point the
real Motorola remote at the receiver and it detects the button presses
properly, so I know at least the receiver portion of the box is

When this is all working properly, the IR receiver box is going to get
hooked up to the backend that's stuck down in the basement, and I only
need the blaster(s) to work.  That's why there's only 1 remote in the
lircd.conf file.

At the moment, I'm not using any channel changing script; I'm just
using irsend at the command line to try to get the STB to do
something, anything.  Here's the gist of what I've tried:

irsend SEND_ONCE Motorola_VIP_1200 INFO


irsend SEND_ONCE Motorola_VIP_1200 2
irsend SEND_ONCE Motorola_VIP_1200 5
irsend SEND_ONCE Motorola_VIP_1200 1

I know that in a channel changing script, there should be some sleep
time between sending buttons, but I can't type that fast at the
command line.  I've also tried all the combinations for
SET_TRANSMITTERS: 1, 2, 1 2, 2 1.

Thanks for the suggestions.
