While the KX3 Utility's Terminal program uses the K3 or KX3's command set
(specifically the KY command), I don't believe many of the popular contest
logging programs exploit this Elecraft-specific capability.
Instead contest logging programs tend to use a technique that works for
almost all radios: Wiggle a serial port modem control pin (DTR or RTS), or
a parallel port pin (a popular technique before Windows made it difficult to
get programmatic access to a parallel port pin without installing a specific
device driver), or through commands sent to a K1EL Winkey chip (or an
emulation of that chip).
>From the radio's perspective, all of these amount to toggling the "straight
key" line.
There may be contest or general purpose logging programs that I am not aware
of that do exploit the K3/KX3 KY command.
It would be a nifty software development opportunity for a logging program
on a NetBook sized computer to use just one serial port connector to the
KX3, and use its serial KY command for CW keying. But I don't think we are
there yet. I'd like to be wrong.

Lance, if I'm reading the posts and the manual correctly, it's not a
software issue. After all, if the KX3 utility could do it, any other program
could be set up to do it too. But as far as I can figure out, there is no
way to key the KX3 from a computer because of the hardware configuration.
Much of the CW that is sent on the air in this non-ragchewing era is being
sent by a logging program or other computer-controlled software.
And note that some contests require a different exchange for every QSO, so
storing the info in the KX3's keyer memory won't work. In those cases, the
solution appears to be the one that Ron proposes, viz. to have an outboard
box controlled by a separate port on the computer. Or just use your K3.
