Hi again, sorry for late response but I was yesterday dismantling my EeePC netbook which is part of the subject.

so my built-in keyboard is a PS/2 one, it seems.
I added that line to wscons.conf (and yes, wscons is enabled by default there), now backspa^W backarrow generates "^H", DEL "^?". However both still erase to the left

I come from Windows, Linux background where BS removed from left and DEL erased to the right. FreeBSD behaves similiarly - Well, it also works that way on X11 on NetBSD. Meanwhile on wscons both remove to the left

My EeePC lacks keypad. External USB keyboard generates "^[[3~" on keypad DEL which seems to have no effect in wscons (writes a tilde), in X11 it's same as the DEL key.
