Well after asking a PPC user, he says the setserial output looks normal
(macs have no UART apparently) and the port and irq looks fine.

Perhaps the cable to the modem is the wrong kind or broken, or the modem
doesn't work.

Can you try the modem with another machine (PC perhaps) to check it?

Also make sure you are using the right port on the back, and apparently
modem and printer cables although they look similar are not
interchangable on a mac (I think the modem one is crossover and the
printer one isn't.)

Are you sure it works in MacOS as it is right now?

Which kernel version are you using?

Could you try:

cat > /dev/ttyS0
+++ATH0 ATE1V1 AT&Q
<control-d>

Which lights are on on the modem?
