That is precisely why I use the separate digital interface.  I built a separate 
relay into my interface that disconnects the microphone when the computer is 
operational sending a SSB message, and the mic is activated and the computer 
message is stopped as soon as I put down the footswitch to manually operate the 
mic.  I can't imagine trying to use the computer during a SSB contest or for 
meteor scatter without the ability to interrupt it.  The programs I have used for 
this look for an interrupt via the serial port's DSR line.

I would think this would be possible with a flexible rig such as the K3, but 
apparently it is not yet incorporated into the firmware.  I don't know if it is on 
a "firmware wish list" or not, but I think it should be.

GL and VY 73, Lance
