cd /dev
sh MAKEDEV cuaa3

should do it if the port is recognized on startup.
Look at /var/log/messages for something like

Dec 23 04:26:48 malibu /kernel: sio3 at [some address] irq 9 on isa
Dec 23 04:26:48 malibu /kernel: sio3: type 16450

Make sure your modem has its irq set to 9 as this is hardwired into the
GENERIC kernel. Or use the "-c" option on startup to set a different irq.
