[Elecraft] N1MM setup help

[Kevin]

I am using my IBM Thinkpad with an older K1EL keyer.  The keyer is 
plugged into the back of the K3 in the keyer socket.  The USB connection 
from the K1EL keyer is hooked to the Thinkpad.  The laptop is hooked 
directly to the K3 via its serial port; yes, a true serial port with a 
DB9 connector.

Now comes the problem: Setting the com ports correctly.

It has been years since I last hooked this together and I just today 
installed N1MM onto the recently installed OS.  I know I need to set the 
com ports to get it running correctly.  One for the serial connection 
and one for the USB connection.  Reading the installation notes for N1MM 
just buries me in information when all I really need is a picture of 
which com ports to use.  The last time I did this I just worked my way 
through all combinations until one magically worked.  Currently I don't 
have that kind of patience :)  Could anyone direct me to the short form 
of the instructions or give me a little hint as to which ports may 
work?  By the way, the OS I am using on the Thinkpad is the last version 
of XP.
