Reading the documentation it's implied and refers to a "control channel". The
thing just does a passthru so I don't know how it could 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 bespecifically supported by the application. Many applications do
not know how to share the radioport with other functions, use the control lines
(RTS, CTS, DTR, DSR) for handshaking, or apply afixed level.

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