Don and everyone,
The RemoteRig RRC actually provides a built-in method to provide this
duplicate CAT data.
Since the RRCs' COM2 are already occupied to tie the two ends together
using CAT, all you have to do is to change each RRC's COM1 to mode-7.
This will duplicate CAT over COM1 and you can use it in for control.
Each RRC will provide the CAT data separately, so you can run a CAT sync
device such as SteppIR, amplifier, etc. on the radio side and a
logging/control program on the control side simultaneously and
independently. Also note that the baud rate on COM1 must not necessarily
be identical with COM2.

Jorge,
You cannot have RemoteRig and the K3 on the same COM port. You must
use 2 different COM ports. Otherwise, the K3 drivers and the
RemoteRig drivers on the RS-232 connection will interfere with each
other.
If you do a study of RS-232 mark and space voltages, you will find
that it is a point to point (one to one) communication. Other devices
may "listen in" to the communications, but they must have all drivers
disabled and set to a high impedance state. The K3 and the RemoteRig
do not meet that criteria, so they cannot co-exist on the same COM
port connection.
The only solution is to use 2 COM ports (one for K3 and one for
RemoteRig), and if they must synchronize, that will need to be done in
the computer - but I don't know of any software application that will
do that synchronization.

Hello Fred
I lost automatically antenna change because I needed to remove my CAT
cable
from K3 to connect remoterig. Of course if I removed remoterig RS232
cable
and connect CAT cable all is OK as I had it before connecting remoterig
That switch A/B is not an option for what I am looking for, I need
both at
the same time
