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.

I've been using TX TEST for this purpose. Your K3 is probably set up
to use DTR or RTS for keying. When the USB enumerator starts up, the
first thing it does is reset all the hubs and endpoints, and this
causes the serial adapter's DTR/RTS to become asserted, keying the K3.
USB may be reset several times, resulting in TX cycles to match.
The only other way of preventing this (that I know of) is to unplug
the serial line at the adapter.
This shouln't happen on a regular COM port, one that's integrated into
the computer. I believe it will *always* happen if there's a
USB/serial adapter in line.

When booting up my PC connected to the K3 it keys the TX several times
during the bootup sequence, I imagine when initialising the various
comports. I need to power up the K3 first before PC boot as I have added LP
Bridge to my PC auto start program list and it wants to see the K3 to
enable the connect port.
Is there a way to auto inhibit TX keying during PC bootup ( eg. placing the
TX into TEST mode)?
I believe there must be a way but can't find it as yet.
