[Elecraft] K3 Bootup sequence?

[Vic K2VCO]

It happens on my computer, with a real COM port. I used DTR keying and allowed the N1MM 
contest logger to generate CW for years, but finally gave up and got a Winkey USB device. 
I am happy I did -- the CW is cleaner, and I don't have to worry about accidentally keying 
the transmitter on boot-up.
