termcap, TERM, vi and cygwin

[esmith <esmith@xxxxxxxxxxxx>]

When using vi via cygwin ssh to DragonFly, the cygwin terminal doesn't stay in sync 
with the server. The curser jumbles text on roll-over, etc... I tried different 
settings for the TERM variable on both. Is this is some kind of termcap problem? How 
should this be fixed? Does cygwin need to update their termcap or does DF need to 
accomodate cygwin in its termcap?
