I just noticed that you're specifying XONXOFF.  The ts450.c default is
RIG_HANDSHAKE_HARDWARE which implies the connection of RTS/CTS lines
between the serial port and IF232 interface (if that's what you're
using).  XONXOFF would seem to require radio protocol support and I've
not seen any of the Kenwood rigs use it.

Looking at the IF232C manual, I see that it calls for the connection of
the RTS/CTS along with TX, RX, and GND lines.  Other than this, I am out
of ideas but the errors shown by rigctl seem consistent with improper
flow control.
