Tnx to Andy and Bob for the feedback on this. Yes the manual says that
the Main / Sub radios must be connected at 115,200 bps, and while it was
some time ago, my testing here seemed to prove it true.
The 890 does install 2 virtual com ports for the USB connection:
standard and enhanced.
I designed the S-BOX for just this type of serial port sharing. It passes
all serial lines straight through from PC (normally) to Radio RS232, and
taps the RXD line (Pin 2) for the KPA500, KAT500, SteppIR, etc. This
works with POLL OFF as long as a logging program is polling the radio
properly.
"I have a TS-890S that has a KPA500 connected to the radio's serial
port. The amp follows the radio, no problem. Very slick.
I also have a TS-590SG that I can use as a second receiver for the
TS-890. For this to work right, the sub RX needs to connect to the 890
via the serial port with
