Tom,
Just a shot in the dark - there are 2 DB-9 connectors on the back of the
P3. Are you certain the one labeled "PC" is connected to the cable
plugged into the PC (or USB to serial adapter)? If so, try another
cable (or adapter).
OK, if you have the K3S connected to the PC via the USB cable, then
there is a slightly different situation (ignore the above). Look at the
diagram on page 18 of the K3S manual. Note well that the connector on
the end of the cable plugs into the connector marked PC and the
connector with two cables emerging from it connects to the XCVR
connector. Unplug and replug the RJ-45 connection and make certain it
is seated all the way.
If that still does not bring success and you have a USB to serial
adapter (or a real serial port on the computer) connect that to the PC
connector on the P3 as a test and see if you can run P3 Utility.

I have connected my P3 to my new K3S and it works very well. However,
now when I try to load my P3 Utility it will not connect to any com
port on my PC.
I'm not new to working with COM ports and PC applications, having
sucessfully written several working applications which connect com
ports, so I set one of my applications to use one of the com ports the
P3 utility will not connect to and stepped through the debugger and
found that the program would connect to all of the com ports I had
tried to connect the P3 Utility to, and found that in all cases the
applications would connect to the com ports that the P3 Utility would
not connect to. In all test cases I set the com port speed at 38400
or greater.
Being one of the first factory built K3S's, perhaps I have stumbled
onto a bug in the P3 Utility.
Thanks for all of all of the great products you provide for me and the
rest of the Elecraft owners.
