[Elecraft] PSE HELP: K3+N1MM+MMTTY

[Sante - IK0HBN]

Hi All,
one of my friend have given several days ago the duty of setting his 
K3 with N1MM and MMTTY. Surely it's a good start for me with this 
radio, but as at moment I'm not an owner of such a cake, I need your help.

Purpose: Using K3 with a single True Serial cable to manage FSK, CW 
and triggering DVK Voice message of K3. This radio has been purchased 
with its internal DVR and I found the G4IFB posting useful to trigger 
DVR memories (http://www.g4ifb.com/html/elecraft_k2_k3.html#TrigerDVR).

I need to know if there is a way to go out in TRUE FSK using the CAT 
cable Computer-K3. I read that CW should be possible, even if CW will 
not be brillant for the delays of WinXP multitasking.

Thank you
Sante
