I can't bind the delete key to delete on QNX Neutrino 6.4.1  PDKSH shells accessed via PuTTy. Please point me in the 
right direction.

My bind settings are as follows:

bind | grep del
^D = eot-or-delete
^H = delete-char-backward
^? = delete-char-backward
^[^H = delete-word-backward
^[d = delete-word-forward
^[h = delete-word-backward
^[^? = delete-word-backward
^X3 = delete-char-forward
^XP = delete-char-forward
ଠ= delete-char-forward

It leaves a ~ where it should have deleted a character. Neither ^[[3~ nor ^? seem to work.
