The latest public K3 Beta firmware (3.94) allows it now to use the K3 internal RTTY functions for an external program. Now it is possible to run RTTY in RUMlog, just the CAT connected to the K3. An audio interface (or a further cable) is not required. RUMlog can use the internal FSK generator and the built in RTTY demodulator. Also you can select cocoaModem as demodulator only. See the Digi tab in the RUMlog preferences.

Using the k3 only, you will not have the quality, flexibility and the comfort like using cocoaModem, but it is okay for few QSOs without any other hard- or software. For tuning you have to use the VFO knob only, it's real old fashioned FSK.

In the K3 you have to use MCU 3.94 or better, this is currently a Beta version!

In the K3 you have to enable the Text Decoder function manually and you have to use the FSK-D datamode!

Very nice!

I am finding that it also works in PSK D even though there isn't a menu configuration for "cM (RX) + K3 (TX)" as there is in the RTTY set up.

I'm sure it won't be as versatile as using cCm and the waterfall for TX & RX but it's interesting and perhaps a mode I might use for chasing a DX station with the filters tight.
