[Elecraft] K3 - should data via the RS232 cable work?

[Dave G4AON]

The current firmware allows for PSK31 and RTTY to be decoded to the LCD 
display and encoded via Morse paddle input, I've even had a couple of 
RTTY QSOs via that awkward route!

I've not seen details of anyone operating data with a K3 via the serial 
cable, a feature that may not yet be available. The programmers 
reference manual mentions it, as does G4ILO's KCommunicate, but the 
latter doesn't currently seem to work on a K3.

Any updates or ideas appreciated.
