i think there is a miss understand: on the ir kb i am pretty using Manchester modulation, and physically the Infra red Led ( i added to the serial kb) is attached to a pic which modulate it with the serial stream it gets on his serial uart port at 9600bps my powerbook has got an Irda port SIR, which i can directly access, from which i can see the scan code the ir kb is sending on every key pressed so the physical layer should be fine the problem is i do not want any Irda "frame" transmitted by higher layer akita add a lot of thing, packing data into "frame" (as the eth0 does, in a similar way, i mean) i do not want any stack ! i just want to direct get char ot of the uart which the ir is attached (and pretty demodulated) i do not understand the pxa_ir kernel module ... i have to study it _______________________________________________ Zaurus-devel mailing list Zaurus-devel@lists.linuxtogo.org http://lists.linuxtogo.org/cgi-bin/mailman/listinfo/zaurus-devel
