I do that a lot. It works great.

What that check means is "use this port to send CW"

I have both of the top boxes checked. There are special reasons for
certain contests where you might want to change that.

Good. Although, if you're not sure that the port you're using is
really com1, check it out. I've had laptops that put com1 only on a
port extender and com2 on the computer itself.

TILT! There's your problem. I'm assuming you want N1MM to send CW.
To do that, left click on the "Set" button for COM1, then choose CW
for DTR (pin4). To run only CW, choose Always Off for RTS (pin 7).
If you want the computer to send PTT to the radio, choose PTT for
RTS(pin7). With DTR Always On, the serial port won't send CW. With
RTS(pin7) Always On, you'll be stuck in Transmit if you set the
radio for PTT on RTS.
Now, go to the Config Menu of the K3 (with a LONG button press for
the second menu) and go to the PTT-KEY setting. To only run CW, set
this for OFF-DTR. To run both SSB with PTT from the computer and CW
from the computer, select RTS-DTR. [This is a WONDERFUL feature
built into the K3 -- you don't need the transistor between the DTR
and the key jack, or between the RTS and PTT. The K3 takes CW
directly from pin 4 and PTT directly from pin 7 -- IF your CONFIG
setting tells it to do so.
Now, I'll tell you what I do. On CW, I run QSK with the K3. Follow
the K3 manual to get there. If you plug a paddle into the radio you
can interchangeably use the paddle and computer keying. For SSB,
RTTY, and PSK, I use VOX, NOT PTT. For RTTY and PSK, I feed audio
from the computer sound card to the radio, and from the radio to
the computer sound card. So I don't use PTT (RTS) at all. Some guys
like to use PTT, that's your choice. I'm a serious contester, and
VOX works for me.
BTW -- if you set N1MM to do both CW and PTT, you can still turn
off CW or PTT or both with the CONFIG setting for PTT-KEY.
