I guess I'm not being clear. I don't think the Mac moves the 
DTR/RTS lines when it boots. I haven't ever seen the K3 go into 
transmit mode when I reboot.

Of course that might be because I have PTT_KEY set to OFF-OFF 
and use VOX for sound card modes except wsjt-x and RUMlogNG 
contest mode. (They use the CAT interface.)
