[Elecraft] [K3] Remote control protocol documentation

[Bob Cunnings]

>From the changes notes for K3 firmware MCU 4.47 / DSP 2.73, 12-2-2011:

REMOTE-RIG SUPPORT:

"One K3 can now directly control another, with one acting as nothing
but a front panel. This "remote rig" mode provides a nearly perfect
emulation of the remote K3's display and controls. (Previously, front
panel emulation was limited by the K3's legacy command set.) The
simplest way to use this is to connect the two K3s together using a
"null modem" cable at the RS232 ports. However, by using a computer or
a third-party hardware as an intermediary, it's possible to control a
K3 over the internet or even a wiFi connection."

"Previously, front panel emulation was limited by the K3's legacy
command set." hints at something new to make remote control more
efficient. Wayne described it in this message posted on 21 Sep 2011:

"Virtually the entire K3 user interface is supported by the new remote-
control protocol. It really feels like you're using the remote K3
itself, including a 100% accurate emulation of the remote K3's LCD
(flashing icons, etc.)."
