[Elecraft] K3 & Remote Rig Questions

[Dennis]

I'm in the process of setting up a remote K3 Twin Station, and
am having a few minor problems.  I'm addressing this to the
Elecraft reflector as I think the problems are correctable thru
the K3 setup.

1. Is there a software command that will put the Control K3
into Terminal mode?  I know I can do it by pushing and holding
in the CONFIG key, and I've been over the Programmers Reference
but don't see either a software command or a <Long Hold> key #
that will do it.  I also don't see anything in the Firmware Update
Section on how to do this.

2. If my Control K3 is in Terminal mode, I'm connected to
the remote unit, I then turn my Control K3 off, do something
else, and come back an hour later and turn my Control K3
on (and it connects again), the audio on my Control K3 is now
on.  The noise is adjustable via the Control K3 volume control,
but there its just noise- just no audio.  If I take the Control K3
out of Term mode to Norm mode, the audio is again muted.
How can I mute the local audio when I turn on the rig?  Again,
I searched through the most current Programmers Reference
on the web, but can't find a software command to mute that
audio, and if I did, I would probably mute the audio at both
the Control and Remote K3s.  The Firmware update area just
says the Control K3 audio will be muted.
