Regarding the beam part of your question, I also had trouble with it.
Someone sent me the following function,
which seems to work ok;
#include "irlib.h"
Err SetBeamReceive(Boolean BeamEnabled)
{
UInt refNumber;
PrefSetPreference(prefBeamReceive, BeamEnabled); // let the preference
manager know
SysLibFind(irLibName, &refNumber);
if (refNumber != sysInvalidRefNum){
if (ExgLibControl(refNumber, irSetScanningMode, &BeamEnabled,0) == 0)
return 0;
}
return -1; // If you haven't returned by now, there's been an error
}
Hope this helps.
