modem not responding to mgetty

There's a 9 pin connector (nothing attached) that I'm not sure what 
it's for, a printer port, and mouse and keyboard connectors, otherwise 
they are all USB ports.  (Hardware is NOT my specialty.  This is a new 
Dell Dimension 3000, if that helps any.)

This remains all that dmesg shows:

# dmesg |grep "^sio"
sio0: <16550A-compatible COM port> port 0x3f8-0x3ff irq 4 flags 0x10 on 
acpi0
sio0: type 16550A
sio1: configured irq 3 not in bitmap of probed irqs 0
sio1: port may not be enabled

I'm starting to think that my modem (US Robotics that I salvaged from 
an old HP I had) isn't detected by FreeBSD on boot.  If so, would I be 
better off getting a new modem that might be recognized?  It's a 56k 
fax modem, IIRC what WinXP was telling me.  (I tried to save $20 by not 
buying a modem installed by Dell, and I knew I was going to regret 
it...)

I'm not sure what that tells me.  Should I be telling mgetty to use 
cuaia0 or cuala0?

(Is there a good way to test a new /etc/ttys and mgetty config w/o 
doing a full reboot?)
