>Description:
The link to the following page in the handbook mentions sio(4) instead of uart(4): http://www.freebsd.org/doc/en/books/handbook/serial.html#SERIAL-CABLES-PORTS . The documentation needs to be updated for FreeBSD 8.x+ as sio(4) is defunct in 8.x+:

wf048# dmesg | grep ^sio
wf048# dmesg | grep ^uart
uart0: <16550 or compatible> port 0x3f8-0x3ff irq 4 flags 0x10 on acpi0
uart0: console (115200,n,8,1)
uart1: <16550 or compatible> port 0x2f8-0x2ff irq 3 flags 0x10 on acpi0
uart2: <16550 or compatible> port 0x3e8-0x3ef irq 5 flags 0x10 on acpi0
