You would need to connect the K3's PC IN and OUT lines to
your computer soundcard and the RS-232 serial interface
for freq/mode info and setting up the PTT/CW.
I believe the only time you will need some other external
interface would be for true FSK. The line for this is on
the ACC connector and should be keyed via an open
collector at less than 5 volts.

So, the FAQ says
The K3 has the features of most high-end "sound card
interfaces" built in. Transformer-coupled stereo line out
is included. This enables you to have the main receiver
and the subreceiver feed into your computer for various
data modes. Transformer-coupled line input is provided,
for various digital modes or other external audio sources
for transmit.
The RS232 serial interface supports RTS and DTR inputs.
These can be configured by use of a set up menu so either
signal can be PTT, KEY or both. This meets the needs of
most data mode and logging programs. We used RS232 to
support users of still-popular DOS mode logging and other
utility programs, as well as computers with legacy ports.
Elecraft also sells a USB-to-RS232 cable that has been
tested with the K3 to allow users of more modern
computers complete access to the interface.
So that means I can simply use the transformer coupled
lines to talk to the computer that is using Mixw?
If that's the case, one wouldn't need a rigexpert if you
had the mysterious USB to serial
whathamacallit/prayerwheel/gizmo?
