You haven't missed a thing, as long as you're talking CW!  The simple 
interface I described is all it takes. Don's embellishment should be fine too 
-- just a slightly different way to skin the cat. Bottom line -- all it takes 
for Writelog to send CW to the K2 via the computer serial port is either one 
transistor, a resistor, and two diodes, or two transistors and two resistors. 

As has been noted, Writelog talks to the K2 just fine.
