You can ask kernel people. Bbox FAQ even tells you how to turn it off
by hacking your kernel.

A hack was removed from init.c (and is now available as "cttyhack" applet).

busybox is about size, and our init.c is still doing some silly things
it should not do. Like setting TERM (not just setting it, but setting it
*differently* for serial lines (TERM=vt102) and everybody else (TERM=linux)!).
This is just silly. init has no business setting TERM.
