I suppose, your device supports only sir.
So you can't use the higher levels of the irda communications.
But of course you can switch the uart to irda and then you are able to
talk sir ;-)
Maybe www.palm.com/devzone/docs/serialma.html can help you for general
serial programming.
This is, how we open the serial port to use sir (dependent on a flag
"UseIrda":
UInt OpenRS232(UInt refNum)
{
Err error;
if (!PortClosed)
return true; // Port is already open!
error = SerOpen(refNum, 0, Baud);
SetSerialSettings(refNum);
if (UseIrda == true)
ComsEnableInfrared(refNum);
PortClosed = false;
return true;
}
Err ComsEnableInfrared(UInt refNum)
{
int e;
e = SerControl(refNum, serCtlIrDAEnable, 0, 0);
return 0;
}
Now you can send your bytes ...
Hope it helps.
