What a coincidence: I was checking the 'stty -a' state during boot and
shell execution when I received your msg! :))

The problem is that the flag 'echoe' is _disabled_ and the flag 'echoprt'
is _enabled_ during boot, and they're the flags that control the BS
behavior (on the screen, that is). Once I forced the "right" state on
these flags from within my C app., then everything works like a charm.

Thanks to all who replied!!
