Re: DTMF Recognition

Hi Tobias,


I use a Fritz PCMCIA Card in my Laptop, with the 49.18 Driver form AVM.

If I use the NCCI in my Facility_REQ I get 0x2002 (Illegal Controller / PLCI
/ NCCI), if I use the PLCI, it will work ...


Maybe that this depends from manufacturer to manufacturer :-( ....

But I wan't to test it on an HST-Board in the next few days, and will keep
you informed...


Kind regards ...


Christian
