Mike,
the microHAM uRouter application provides two sets of virtual serial
ports per rig. I have been using this facility with issues for many
Years. Proper arbitration of CAT commands is provided. Obviously
conflicting commands cannot be reconciled, but control from two
applications is reasonable and practical using this application with
devices like the micro KEYER 2 and 2R+.

Reading the documentation it's implied and refers to a "control

possibly share the rig with CAT control. That's likely why he got a
bus collision error. I also can't find a single youtube video of
anybody doing CAT control using two programs. The 2nd cat port is
just for monitoring.
Unless I'm reading the wrong documentation. Nowhere in the docs does
it say you can have two CAT control channels. If it did they'd be
bragging about it for sure. They just don't explicitly state the
limitation (should be obvious to the casual user I'm sure :-)
From https://www.microham.com/Downloads/U2_English_Manual.pdf for example:
*The virtual COM port assigned for Control* can be shared with CW
and/or PTT but sharing must be specifically supported by the
application. Many applications do not know how to share the radio port
with other functions, use the control lines (RTS, CTS, DTR, DSR) for
handshaking, or apply a fixed level.

Mike,
that's not correct. The microHAM uRouter provides two sets of COM ports
per radio.
