Yes, I ran into that parameter already. But a simple try with 
frequency = 0 failed ... naive I now. ;-) ... currently I'm using
a workaround with some further hardware connected to the irout_pin
of the Raspberry Pi.

My next step would be, to enable frequency = 0 in the source and try
to fix what fails then. But if you did that already, it would be very
nice, if you could share your modifications?

Thank you very much for your help!
