B&O remotes use a carrier frequency of 455 kHz (yes 455 kHz) and a modulated
pulse with a length of 200 ms.
I realize the difficulty in learning B&O commands at the 455 kHz frequency,
however the IR data transmissions of the B&O commands have already been
captured with an oscilloscope, so no learning capability necessary. I
also, have the timings and data format for the B&O protocol. The
documentation is located in the following files:
IMHO, All that remains to do is:
1) Format data in the config file format that the lirc program can use.
2) Find or build a IR transmitter that will operate at 455 KHz.
Does this sound like it might work? Any advice on building the transmitter?
Thanks for taking the time to read this email. Any information or advise
that you can give me would be greatly appreciated!

lircd won't understand the B&O protocol (yes, one more different
protocol...). But, you could make a raw mode config file manually if you
have the signals.

You could try to use a simple IR diode like described on the homepage and
set " frequency 455000 " in the config file. The driver will then generate
2usec pulses. That would be equal to 500kHz. I don't know how exact this
value really will be and if it will be tolerated by the receiver. Check
that your IR diode is fast enough.

Not impossible, but unlikely to work.
