[Elecraft] K3 to arrive soon...what do I need ...???

[K4GM-George]

I recently sold an Icom 756 Pro II to make way for my K3. When it 
arrives I would like to be able to control the K3 from N1MM and 
Logger32. Up to now I have  used a RigBlaster Pro between the computer 
and the radio.  I would also like to generate my cw using a microham 
Winkeyer.  Finally I also need to generate RTTY (fsk) from N1MM and 
Logger32  to feed to the K3. While I  might find using the built-in RTTY 
facility appealing for ragchewing, I know that I would want to generate 
the FSK externally from N1MM when contesting.  From what I have read I 
think I would no longer need the RigBlaster but would just use a direct 
sound card connection.  How do I control the radio via the PC??  Do I 
just use the RS-232 connector or the ACC connector??   I'm trying to 
determine whether I need to buy or make cables.... 73, K4GM George
