[Elecraft] K3 CAT commands

[David Ferrington, M0XDF]

I've just been reading an previous posting by KD8CGH, in which he posts

here is a short CAT command that I attached to a button I labeled "tuner"
PC020;
SWH16;
@ 1000;
SWH16;

The K3 programmers manual says about @
"! and @ * (Direct Main/Auxiliary DSP control)
Note: These commands are implemented, but full documentation is not yet
available."

It appears @ 1000; waits a period of time, possible 1000mS

Can anyone enlighten me please?
