Ah, okay.  This is a server, so redirection is probably the main issue.  Putty has vt100, vt400 and a variety of other emulations, so good to know that vt100 is what I need.

As for the "jumpy cursor", is this a server? It sounds like Console Redirection is turned on in the BIOS. That doesn't play well 
with serial console.
