None of the WLAN cards support PCF. They are 'PCF-aware' which means that can decode PCF frames and update their NAV accordingly but they can't really respond to a PCF-Poll or any other PCF frame. In fact, none of the APs support PCF. I don't know where you got your info but since PCF was an optional part of the standard almost no one bothered to implement it. There were a couple of devices early on that did have some rudimentary support for PCF but since no one was using it the next versions were DCF-only. - Harshal ------------------------ Yahoo!
