Ok, just a summary, from an unstable box
ASCII DEL: 
- works in local screen (4.0.3-13)
- doesn't work via ssh to an etch screen (4.0.3-0.3+b1)
- works via ssh to a lenny screen (4.0.3-11)
- works via ssh to a rhel5 screen (4.0.3-1.el5)
- doesn't work via ssh to a rhel3 screen (3.9.15-10)

Automatic:
- doesn't work in local screen
- doesn't work via ssh to an etch screen
- works via ssh to a lenny screen
- works via ssh to a rhel5 screen
- doesn't work via ssh to a rhel3 screen

Control-H:
- works in local screen
- works via ssh to an etch screen
- works via ssh to a lenny screen
- works via ssh to a rhel5 screen
- works via ssh to a rhel3 screen

This looks that the perfect stuff for me, except that it breaks in
vim/etch.

Escape-sequence:
- doesn't work in local terminal
- doesn't work in local screen

(no real point to dig further then).

HTH,
