Another thing you might try is disabling the getty there, and running
minicom or screen on it.  Then you can type at it and see what, if anything
appears on the terminal, and vice versa.

I'm most familiar with minicom.  It has little menus you can use to set
things like baud rate, parity, etc (^A Z P will get you the communications
parameters menu).

No guarantees that this will work, but it does give you better control over
the host side of the connection so you can experiment more easily.

Also, have you considered things like the cable might be bad?  Although
what you're seeing really resembles what I was seeing before I got the
baud rates straightened out.
