Delete key not working "normally" in Emacs console mode

Sent this to misc@ a couple of days ago but so far no response. Maybe I
should have sent it to sparc@ but I think this is a generic terminal issue I
don't know how to fix. In case anybody found the same thing on sparc, here
goes.

I am running OpenBSD 5.1 SPARC (32 bit) under QEMU. It seems to work
perfectly except for a couple of minor annoyances one of which may be QEMU
related/fixable. The other issue is the following:

In Emacs 23.4.1 -no-x from packages I am having a problem getting both
backspace and delete to work correctly at the same time, correctly being
defined as backspace causing the cursor to move to the left and consume
characters and delete as remaining in the current column and consuming
characters to the right. Terminal type is sun (default).

Can anyone help with this please? Thank you.
