Hi Walter,
TERM="xterm" is a reasonable default if you are running xterm.

You might loose color or unicode on some old machines. You can then
try xterm-unicode, xterm-256color, rxvt, rxvt-unicode, etc or even
better delve in to the terminfo database. The only rule is that
terminfo on the remote machine has to have the TERM
profile you have set. You can also set the TERM on the misbehaving
machine(if it's a bug) or copy the profile from your terminfo database
to the remote machine database and fix it that way.
