It shows irq9, but that's not from info obtained in the probe. It's
info established at kernel build time from the config.

None of the flow control stuff is different between my setup that
works and my setup that fails, so I don't think I want to look
there. The only differences between the working and failing setups are
the irq number and I/O port addresses for the modem's serial port. At
com2/irq3 (for example) it works, and at com3/irq9 it fails.
