I don't use any of those files, but I _did_ do some rooting around.
stty(1) reports that the erase is setup differently on the two xterms,
as you surmised. 

The termcaps match, and both xterms are of a type TERM=xterm as
expected. I suspect that /dev/ttyv0 and /dev/ttyp0 are configured
differently, possibly through gettytab. I'm not really sure.


I've added the above line to my zshenv file so that both local and
remote xterms get the same environment. So I _have_ fixed the problem.

Thank you for the useful guidance,
