k3S usb software silenced sidetone and no rf out

[IK4EWX]

After installing N1MM contest program, before I used only my TR4W software,
trying to transmit CW from N1MM or TR4W simply commutate RX-TX (qsk or vox)
on the K3S but it doesnt put rf power out nor give the sidetone - that
before I used from the rig, driven via the usb cable.
Rf power is normally out and sidetone also is ok only when  keying the K3S
with my paddle or keys.
I think that N1MM has changed something on the USB/com3 of the PC or on the
rig config (but this seem normal, I even recharged the firmware this
morning).
What do you thing about this problem? Anybody can help me?
Many thanks, 73,
Ian IK4EWX

I have found that setting the config parameter PTT-KEY at OFF-RTS, the K3S
keyed by TR4W software returned to transmit with rf ouput and with sidetone.
I make the mistake of not taking note of the previous value, but setting
OFF-RTS seem to have solved.
Can it be that N1MM+ software changed this parameter in the K3S config?

It is not likely that N1MM+ changed a configuration value in the K3S
(I can not find any command that will allow a logging program to set
that configuration).

Note: the normal configuration for CW and PTT when using the RS-232
*or* USB virtual port with most software is PTT on RTS and CW on DTR.
For the K3/K3S that is CONFIG:PTT-KEY = rtS-dtR

You said:

No, it cannot.

You need to set the N1MM+ configuration for the radio control port and the
CONFIG:PTT-KEY menu item in the radio to match one another.

For example, if CONFIG:PTT-KEY is set to OFF-RTS, then in N1MM+ you must
configure DTR to Always Off and RTS to CW.

Or, if you have configured DTR to CW and RTS to Always Off in N1MM+, then
you must set CONFIG:PTT-KEY to OFF-DTR.

With the homebrew circuit (opto-isolator X 3, one each for PTT, Data/FSK
and CW) I'm using, I chose to take the CW keying directly to the key
port of the K3 (in parallel with the hand key, plus there are paddles). 
That allows me to leave Config: PTT Off-Off.

This has worked really well, except the OS wake up still keys the
transmitter during the discovery phase of boot up.  That apparently
can't be avoided (so I put the TX in test mode, if I'm in the shack).  I
use real serial ports as USB has more problems in QRO RF.

This works in HRD and MMTTY.  For FT8, I have to switch from FSK D (or
AFSK A) to Data A (or just use AFSK for RTTY and leave it alone).

That cat still gets skinned and 'normal' is overrated.  ;-)

For those who have a K3S or a K3 that has been upgraded with the KIO3B
option, the "fix" for the problem of the computer 'wiggling' the DTR and
RTS lines when the computer is turned on is to download MCU 5.33 or higher.

There is a SAFE MODE to prevent just that - read the Firmware Release
Notes for MCU 5.33.

"Safe" mode also works with a standard serial port and an unmodified K3.
