Actually, ExgControl is the proper thing to use. If you look at the
documentaion on prefBeamReceive under the PrefSetPreference api, you will find:
"This preference is currently not used. Instead, use the ExgControl
function with one of the constants described in IR Control Constants."
Here is what I used to enable beam reception
// Enable IR beaming and return former state
Boolean EnablePalmBeam() {
IrStatus error;
Boolean Pref;
UInt16 beam_ir_ref;
UInt16 beamLen = sizeof( Pref );
error = SysLibFind( irLibName, &beam_ir_ref );
if ( error != errNone )
return 0;
// Get current state of IR beaming
ExgLibControl( beam_ir_ref, irGetScanningMode, &Pref, &beamLen );
// If it is off, switch it on but return original Pref value
if ( Pref == 0 )
{
Pref = 1;
ExgLibControl( beam_ir_ref, irSetScanningMode, &Pref, &beamLen
);
Pref = 0;
}
return Pref;
}
Hope this helps.
Doug
