If you want to do only PTT via the RS-232 port you want 
RTS-OFF.  

There are two signals available ... the VFO B area shows 
PTT - KEY (Key is CW).  The options are: 

 Signal:   PTT    CW  
           OFF - OFF   (no PTT or CW via RS-232)
           RTS - OFF   (PTT only via RTS) 
           DTR - OFF   (PTT only via DTR)
           OFF - RTS   (CW via RTS - NO PTT)
           OFF - DTR   (CW via DTR - NO PTT)
           RTS - DTR   (PTT via RTS, CW via DTR - N1MM/WriteLog)
           DTR - RTS   (PTT via DTR, CW via RTS)

I would set the rig to RTS - DTR for N1MM and configure 
DXLab/Commander/WinWarbler to PTT on RTS and use the "KY" 
support (CW must use VOX/QSK).

FSK can't be done without a TNC, a device like the microHAM 
interface that generates FSK externally or a USB port with 
the proper (EXTFSK) driver in MMTTY.  The USB port requires 
a transistor to convert the +/- 10V from the RS-232 port to 
open collector switch closures for the FSK input of the K3. 

FSK is not an absolute requirement for RTTY as you can use 
AFSK (tones) if they are handled correctly.
