Yes. The K3 can be set to take CW and/or PTT from DTR and RTS lines of 
its RS232 connector. This works whether the computer connection is a 
real hardware port or a USB to RS232 port. The menu setting that I gave 
Bruce in my response was to take CW from DTR. This works quite well IF 
the computer-generated CW is not chopped up by other activity on the 
computer stealing processor cycles. N1MM, both original and Plus 
versions, have that issue, and I remember WL doing that when I was still 
using it 6-8 years ago. The key, of course, is to get rid of all those 
other processes.
