I think i'm doing something wrong :-), tip -38400 com1 works fine,
Type '?' for a list of commands, 'help' for more detailed help.
OK boot -d

Ready to go.  Enter 'tr' to connect to the remote target
with /dev/cuaa0, 'tr /dev/cuaa1' 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.
