Hm. I'm on tao2 now, ssh's into tao. On a Konsole on tao2,
the [backspace] key works fine--from the CL. Your suggestion of
using the literal ^V^? makes no difference. The only thing that
does, is selection the "freebsd console" from the Konsole
Settings -> Keyboard drop-down, as I wrote to Chad a few minutes
ago. So closer.

I'm not touching the termcap file unless it's an (abs) last
