И вот тут мой мог ничего не соображает. наверно сказывается вчерашняя травма шеи, не могу головой поворачивать в обще:

Ready to go. Enter 'tr' to connect to the remote target
with /dev/cuad0, 'tr /dev/cuad1' to connect to a different port
or 'trf portno' to connect to the remote target with the firewire
interface. portno defaults to 5556.
Type 'getsyms' after connection to load kld symbols.
If you're debugging a local system, you can use 'kldsyms' instead
to load the kld symbols. That's a less obnoxious interface.
