You will need software that understands the KY command to transmit  
RTTY data (Baudot, not ASCII) through the RS-232 port.

RUMped by DL2RUM supports this, but even RUMped uses a software modem  
on the receive end (i.e., needs one audio cable).  Since you mentioned  
N1MM, you are most likely not using Mac OS X, which RUMped needs, so  
it might not work for you anyway.

I recommend that you set the rig and software up to use AFSK instead  
(either with AFSK-A or DATA-A mode depending on whether you use agile  
waterfall transmit).  Wire up a sound card to the K3 using two audio  
cables, then adjust the audio drive and VOX gain properly and you  
should be good to go.
