I'm a newbie to FreeBSD so I don't know exactly where you should check.
However, it appears to me that some communication parameter is not the same
on both sides of your connection.  When I have seen "garbage" output in the
past, it usually has to do with 8 bit communication on one side and 7 bit
communication on the other side.  Also check parity and stop bit settings.

HTH,

Drew
