This isn't the whole story. First, yes it is possible to set "PTT & FSK" 
to the FSK port; the "No" was in response to the "then use the Radio 
Command setting" part of the question.

Next, MMTTY cannot use the CAT port to control PTT by radio command, but 
I believe there may be a way to fool MMTTY into using a third port for 
PTT. For example, if the TI5 is using COM3 for CAT, COM4 for PTT, COM5 
for Winkey and COM6 for FSK, then in MMTTY, select COM6 as the PTT & FSK 
port. Under the Radio command button, set COM4 (*not* COM3) as the Radio 
command port, check the check box for PTT under DTR/RTS, set Group at 
the bottom to Clear, the Model to NONE and make sure all of the Command 
boxes are clear. This should tell MMTTY to use RTS (and DTR) on COM4 for 
PTT. MMTTY will not only toggle PTT from the TI5, it will also close the 
CW key at the same time, but with most radios this should not matter 
when the rig is in RTTY mode.

If you do this, you must leave COM4 unconfigured in N1MM Logger, i.e. 
you will not be able to use COM4 from N1MM Logger for PTT or serial port 
CW. If you want to use COM4 from N1MM Logger in modes other than RTTY, 
you should leave MMTTY's Radio Command port set to NONE and configure 
N1MM Logger to use COM4 for PTT, as I suggested in my previous post.
