[Elecraft] N1MM and K3 interface ?

[Jack Colson]

I just tried to interface N1MM software with my K3 using the Elecraft 
USB to RS-232 cable. Problrm is that as the program comes up the PTT 
line is asserted.  I tried monkeying with the DTR and RTS settings 
resulting that the transceiver continued to be in the transmit mode.  I 
could only release rig by shutting down N1MM software.

Now this must be simple!  HELP !
