All that is needed for K3 control are TXD, RXD, and Ground.  DTR and RTS
are used for PTT and Key-in (see page 18 of the manual), not serial
communications.  The problem, as described earlier, is that the program
is setting the mode first and then the frequency.  I've asked other
program authors to reverse those two commands and they have willingly
complied.  The sequence is important on the K3 as mode is retained on a
per band/VFO basis and it acts on commands as autonomous units.  To me
it seems as though setting the freq first and then the mode should be
the proper sequence for all rigs, not just the K3.  Perhaps programs
should be smarter (and some likely are) where after changing the
frequency the mode is polled and then changed only if necessary.

The only problem with USB to serial adapters when controlling the K3 is
apparently with drivers on certain legacy operating systems.  I've used
a couple of Prolific based converters on my Linux machines with nary an
issue.
