[TriLUG] Capture Terminal Session without Control or Color Codes

[Stephen P. Schaefer via TriLUG]

Try
export TERM=DUMB
...after the ssh.  The dumb terminal doesn't have any escape codes; vi will be ugly and barely functional.  less or more will be ugly but meh.

This is why I can still remember six ed commands :-)
