Environment:
Mutt: Version 1.4.2.1i
OS: Solaris 9
Hardware: Sun V250 with the Type-6 Keyboard

Problem:
I am having a key binding problem on this system that I did not
experience on my previous SPARCstation-20 with a Type-5 keyboard
running Solaris 8. I have bindings like the following defined:

bind generic <Esc>[313z previous-entry # Keypad 0 Key
bind generic <Esc>[314z previous-entry # Keypad 1 Key
bind generic <Esc>[315z bottom-page # Keypad 2 Key
bind generic <Esc>[316z next-entry # Keypad 3 Key
bind generic <Esc>[317z previous-entry # Keypad 4 Key
bind generic <Esc>[319z next-entry # Keypad 6 Key
bind generic <Esc>[320z previous-page # Keypad 7 Key
bind generic <Esc>[321z top-page # Keypad 8 Key
bind generic <Esc>[322z next-page # Keypad 9 Key

I am running mutt(1) in an xterm(1) window and these are the correct
escape sequences for these keys as defined in a customized terminfo
entry. This has been validated by editing a message and seeing that
all the proper escape sequences are being emitted. I have similar
keypad mappings in my vi(1)/vim(1) startup file and there, every key
works without a hitch.

These mutt bindings worked just fine on the older system, but on the
new machine all the bindings work except for keypad keys 1, 3, 7 and 9.
When these keys are pressed, mutt reports:

Key is not bound. Press '?' for help

However, when I press '?', I see the following:

Generic bindings:

[...]
<Esc>[314z previous-entry move to the previous entry
[...]
<Esc>[316z next-entry move to the next entry
[...]
<Esc>[320z previous-page move to the previous page
[...]
<Esc>[322z next-page move to the next page
[...]
<Home> first-entry move to the first entry
<PageDown> next-page move to the next page
<PageUp> previous-page move to the previous page
<Enter> select-entry select the current entry
<End> last-entry move to the last entry

I have a suspicion that the problem stems from the switch to the Type-6
keyboard. Note that these four non-working keypad keys are also marked
<End>, <Pg Dn>, <Home> and <Pg Up>. However, the other keypad keys also
have multiple functions and they continue to work. (Note: The Num Lock
function is off and has been disable using xmodmap so that it will never
be turned on accidentally.)

Does anyone have any insight into this problem and can you suggest
anything else to investigate or a possible work-around.

Thanks for any help you can offer.
