Most devices in the kernel are accessed through ``device special files'',
which are located in the /dev directory. The sio devices are accessed
through the /dev/ttydN (dial-in) and /dev/cuaaN (call-out) devices. FreeBSD
also provides initialization devices (/dev/ttyidN and /dev/cuaiaN) and
locking devices (/dev/ttyldN and /dev/cualaN).....and so on (handbook)
