I have found fldigi to be quite confusing to set up for CAT, the software is
great but the rig control options and PTT possibilities confused me.  Once I
began to think about it more, it made more sense. Of course, all of this
would have been less confusing if I had read the guide for beginners that is
included in fldigi but heck, I never read such things!

In Fldigi  a user has several options. These options include deciding
whether your rig needs a separate circuit to place your rig in transmit, or
whether you want the rig-in-transmit (PTT) function to be handled by CAT
control,  and thus a need for only one comm port to be used.  Additionally,
if you set a PTT option, you need to determine if it requires RTS , DTR,
etc.  Some rigs can do PTT via CAT control and some cannot, so this needs to
be determined as part of setting up fldigi and other digital mode
applications.

The Kenwood 570 (and most other Kenwoods ) CAN do PTT via CAT control.  So
you can set Fldigi to control your rig and PTT via use of one comm port and
the correct use of other comm port parameters.  However , one option that
Fldigi gives is the option to use HAMLIB's setting for rig control.  This
uses pre-programmed XML instructions to communicate with your rig.  To
establish preprogrammed XML for every rig that is on the market takes a lot
of time.  Not all rigs are fully coded for Hamlib , you will see in fldigi
that some are "stable" (coded, tested, and reported to work well) and some
are at "beta" or alpha level.  I have found the TS2000 hamlib file to not be
very reliable, in Fldigi it is marked as "beta".

As recommended to this group on several occasions by Skip Teller, use of the
other rig control methods in fldigi often results in better operations .
Rig CAT , with a file for your radio , is usually suggested.  For my Kenwood
TS440 and Kenwood TS2000 I use RIG CAT or Hamlib with ANOTHER option,
Hardware PTT.  That requires use of a separate comm port for PTT but I find
it more reliable than some of the beta/alpha rig control XML files that
exists for my radios.

That's the long reply to Danny.  A simpler reply would be that for most
Kenwoods using Fldigi  do the following...

Go to CONFIG/RIG CONTROL
CLICK on HAMLIB
Check "use hamlib"
Select a comm port
>From the drop-down list of rigs, choose Kenwood 570D (stable)
Choose a baud rate that matches the baud rate you have set in your rig (I
use 9600) many Kenwoods have 4800 as the default.
Do NOT check PTT via HAMlib.

Save/close.

Now in Config go to Hardware PTT
Select a second comm port, one that is different from the one you are set
under hamlib
Click on the tiny diamond next to :use separate serial port PTT"
Check use RTS
Initialize
Save/close
