Make sure the modem isn't set for the same interrupt as the com3 
device; FreeBSD doesn't allow interrupt sharing for sio devices.
Also, make sure that FreeBSD correctly understands what interrupt
is being used for each device.  The kernel configuration editor
you get when you boot with the -c flag will allow you change IRQ
settings for the sio devices.
