Ok. Now we're talking. I do have parport_serial and parport loaded. Knowing to look at ttyS[45] helped.
523 > setserial -a /dev/ttyS4
/dev/ttyS4, Line 4, UART: 16550A, Port: 0x8000, IRQ: 11

       closing_wait: 3000

*524 > setserial -a /dev/ttyS5
/dev/ttyS5, Line 5, UART: 16550A, Port: 0x8400, IRQ: 11

I'm almost there. Now if I run

pilot-xfer -p /dev/ttyS4 -b .

or also on ttyS5

instead of saying Unable to bind to port:
I now get the correct message:
Listening for incoming connection on /dev/ttyS5... But if I then hit the button on the Palm, they both just hang there. Any idea what I can do next? Is it still possible that this is not a supported card?
TIA

Maybe kudzu needs to detect the palm or you need to specify the desired baud rate. With cameras, the camera program detects the camera. Do palm pilots use a similar program?
You know the com ports anyway, a little progress.
