The file is /boot/device.hints. For each serial port, the
following dataset has to be completed:

	hint.sio.<N>.at="isa"
	hint.sio.<N>.port="0x3F8"	<---+
	hint.sio.<N>.flags="0x10"	<---+--- set up
	hint.sio.<N>.irq="4"		<---+

Still, I don't know how to determine the correct addresses
and IRQs, maybe the documentation belonging to the expansion
card can help...

If I see this correctly, each serial port should then be
visible as a /dev/cuad<N> device file.
