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.
