When your CW speed gets faster, you'll understand. The issue is how N1MM
sends CW on the serial port, which can get choppy when it is interrupted
by other software running on your computer. WinKey is a very good way to
send CW from a computer. It works quite well for me.
At low speeds, and under the "right" conditions on the computer, you can
send CW on the DTR pin of the serial port. It even works with USB to
RS232 adapters. You need a simple transistor inverter to convert the
keying signal to a short between the keying line and the chassis.
Collector to keying line, emitter to chassis, DTR through 4.7K to the base.
