[Elecraft] Use of DB9 Switch with K3?

[Luis V. Romero]

GOOD suggestion!  While I don't swap cables, I just flip one switch on the
serial selector switch, but this is a good thing to know... Does this mean
that I can use K3-EX CONCURRENTLY with N1MM via Router on a separate com
port, Joe? 

That would be really great!  A GUI for the radio!

I will give this a try!

But it STILL means I must retain my other com port for software updates, as
it is still not recommended to do this through router, correct?
