unlikely - I dealt with that a few years ago:

hmm - lxterm would be vte, which of course does not support 8-bit controls.

What I recall of the PuTTY FAQ (a specific pointer would help) is that
it's roughly comparable to rxvt - implements about 80% of VT100, but
is not a VT100 emulator due to differences in the way it does line-wrapping
(apparently because at the outset its developers were attempting to match
the SCO console).
