[Elecraft] CW keying circuit

I use a simple single transistor keyer in conjunction with the "Auto-Detect" 
feature as described in the K2 manual to use both the computer and keyer 
paddle with N1MM.  It runs directly off a "native" serial port on an old IBM 
laptop as well as off a USB to Serial Converter Cable used on a "new" 
laptop.  It works fine on either.

The simple single transistor keyer is described in the Help section of the 
N1MM program as well as other places.  To see a photo of how all this is 
cabled together you might want to look at my Elecraft photo album at:

I want to be able to do computer-generated CW on my K2, using software such 
as

Can someone send me, or point me to, a CW keying circuit for a COMM port 
that
will work with the K2?
