This will be kind of strange for lirc_zilog (aka lirc_pvr150). It
supports IR transmit on the PVR-150, HVR-1600, and HD-PVR. I don't know
if transmit is raw pulse timings, but I'm sure the unit provides codes
on receive. Occasionally blocks of "boot data" need to be programmed
into the transmitter side. I suspect lirc_zilog will likely need
rework....

True.

I didn't quite understand that. Can you provide a little more info?
Thanks,
