This is a remnant of days long gone when the PC - DOS and early Windows systems
used serial-port connected mice. It used the sequence to detect the presence of
a mouse. The Mac has never used asynchronous serial-port based mice, instead
using a special bus, followed by ADB in early Macs
I guess I'm not being clear. I don't think the Mac moves the
DTR/RTS lines when it boots. I haven't ever seen the K3 go into
transmit mode when I reboot.
Of course that might be because I have PTT_KEY set to OFF-OFF
and use VOX for sound card modes except wsjt-x and RUMlogNG
contest mode.
The real question is the name of the right fielder?

Bill,

The K3 now has a SAFE mode that disables DTR and RTS until it receives
some command like polling for frequency, mode, etc. from your software
On my Mac system, it doesn't seem to matter whether the radio or
the computer starts first. The USB interface to my upgraded K3
is powered from the computer with enough functionality that the
computer recognizes it without the radio being on.
In any case, start wsjt-x last because it will try
Computer first. (This initializes the com ports)
Then radio. (Radio needs the com ports)
Now the software. (Now that radio has its necessary connections, start the
software which can now find the radio and other necessary connections. )

That wasn't me, but...the optimum order is computer, then K3, then WSJT-X.
The reasons: Well, obviously the computer has to come before the software.
The process of starting up the computer causes various signal lines on the
serial port used for radio control to be toggled briefly, which can
A while back, someone commented upon the correct order in which to power up
when running WSJT-X, but I can’t remember. It was either K3S first, then
computer and software… or the other way around.
Please refresh my memory. And, by the way, why is it the way it is?
Cheers.
