Not sure about a Treo, but on older devices, I use:
Boolean HwrBacklight( Boolean set, Boolean newState ) SYS_TRAP(
sysTrapHwrBacklightV33 );
Boolean isOn = HwrBacklight( false, false );
and
EvtEnqueueKey( vchrBacklight, evtNulKeycode, commandKeyMask );
to turn it on
I first use:
if ( ( FtrGet( sysFtrCreator,sysFtrNumHwrMiscFlags, &feature ) == errNone ) &&
( feature & hwrMiscFlagHasBacklight ) )
to determine if there is a backlight at all.
