Hey! I am new to Ir programming and am trying to learn.

     Here is the prototype for IrOpen
Err IrOpen (UInt16 refnum, UInt32 options)

I understand basically what this does and what to put in for the second arguement but 
what about the first? Can I please see a working example of this?

I say IrOpen (UInt16 refnum, irOpenOptSpeed115200)

But what do I put in for refnum?  Also, can someone please give me advice on what 
speed I should use? Any specs. I know I know check out www.Idra.com but I just want to 
see what you all think. Thanks!
