No GPS. An old Kenwood TS440S, has antenna tuner but no external
digital control. It also has AFSK in and out, as well as a DIN
connector with everything at one point, date, ptt, mic. mute,
etc. I plan to use that.

I would hesitate to send image files to the list, can send to
your address?

[root@box9 bobg]# setserial -g /dev/ttyS[0123]
/dev/ttyS0, UART: 16550A, Port: 0x03f8, IRQ: 4
/dev/ttyS1, UART: unknown, Port: 0x02f8, IRQ: 3
/dev/ttyS2, UART: unknown, Port: 0x03e8, IRQ: 4
/dev/ttyS3, UART: unknown, Port: 0x02e8, IRQ: 3

So /dev/ttyS0 looks good to me ...

That would probably be an imposition on your time but would
provide assurance that the function works.

Additionally I have yet to see transmit audio from the computer
while running FLDigi, I do get it from psk31lx. I have not had
keying signals from psk31lx either but have not devoted much
time to investigating that, it may be a configuration problem
and I haven't found much documentation in that area.
