Doug,
Are you attempting to send PSK31 from the K3 Utility Terminal window?
Or from another application?
If from the K3 Utility, there is no need for DTR or RTS because K3
Utility sends the TX command via the RS-232 com port as a command.
If you are using some other computer application, you will have to set
things up in that application to properly key the K3 - the number of
applications and the way they initiate transmit is too wide and varied
for an easy email answer, consult the help file and on-line information
for your application.

I have a full K-line setup (K3, P3, KPA500, KAT500) and I've been
trying to get the K3 working on digital modes. I can't seem to get it
to transmit. Using the K3 Utility, I can verify the K3 at a
particular com port. Firmware updates work fine. I can read PSK in
terminal mode. But, when I click on the transmit button, the K3
doesn't switch to transmit. I have the PTT menu option set to DTR
and, in fact tried every variation of DTR and RTS with no difference.
I have tried both FTDI USB-to-Serial adapters and a genuine, built-in
serial port - all of which work on everything else. I'm missing
something I guess. I just don't see it.
