[Elecraft] MMTY settings for K3S

[eric norris]

I am trying to setup standalone MMTY to run rtty.  Does anyone know the super-secret settings in mmty OPTIONS--SET UP TNC EMULATION MODE?
I have assigned the K3S' sound card.  I am in DATA AFSK mode, 45-45 baud,  915 (I like it low) 170hz shift.  I appear to be receiving (though who knows, no rtty signals).  Port # is correct.
Help a Noob.  Bonus points for how I set rx text to something larger than 2pt--you know, human-readable.
Thanks!
