[ICOM] Splitting the CI-V data stream

[Dave AA6YQ]

If you turn off the rig control application's polling and rely instead on
enabling "CI-V transceive", then the rig control application can't display
anything but the transceiver's current frequency and mode, e.g. no RX
bandwidth readout, AF and RF gain, RF power, S-meter, etc.

Maybe turn off the polling of the PC software and let the Transceive
setting of the CI-V report to the PC the Frequency and mode.
As I remember your stuck with transceive needing to be enabled so the
PW-1 follows the transceiver around in frequency and band.
I wrote one of the original write-ups how to get the PW-1 and a
Transceiver to connect and use CI-V control, was a matter of starting
one before the other but that's as far as I went with it. AND is been 10
years ago.

I do remember the Transceive was an issue when tying two or more
transceivers together as what you did to one the others would follow as
far as they could, generally the mode would follow.
