StartApplication loads the IR library, opens and binds a port, saving
the information in the variable irref so it can be used elsewhere. This
is the first step in creating the IrDA link.
//
// Loads the Infrared Library and opens and binds the port.
//

static Boolean StartApplication(void )
{
if (SysLibFind(irLibName,&irref) != 0)
{
FrmAlert(IrLibProblemAlert);
return false;
}
else
{
if (IrOpen(irref,irOpenOptSpeed115200) != 0)
{
FrmAlert(IrLibProblemAlert);
return false;
}
}

IrSetConTypeLMP(&connect);
packet.buff = (unsigned char *)"Data";
packet.len = 4;
IrBind(irref,&connect,callback);

return true;
}
StopApplication unbinds the port, disconnects, and closes the IR con-
nection.

//
// Shut down connections, close the library
//

static void StopApplication(void)
{
IrUnbind(irref,&connect);

if (IrIsIrLapConnected(irref))
IrDisconnectIrLap(irref);
