There is no such thing on this machine.

It is a Portege 610CT and does have one internal serial port, one
internal printer port and the docking adapter.

Ok, this is the hint I seemed to need: In the kernel configuration I
have:

sio0 at 0x3f8 irq 4
sio1 at 0x2f8 irq 3

But the default (0x1) configuration for the modem had it at 0x3f8.
I changed ætc/pccard.conf to use configuration 0x3 which uses 0x2f8
and the problem seems to be solved.

Thank you very much

Marko
