This is a feature of the VT100 emulation.  The keypad of a VT100 terminal
functions in two modes:  "normal mode", in which each key transmits the
symbol printed on the keycap, and "application mode", in which each key
sends an escape code (for example, keypad-0 sends "ESC ?p", keypad-enter
sends "ESC ?M", etc.).

Apparently Pine is switching your keypad into application mode, and not
switching it back on exit.

The terminal switches between modes when it receives one of the following
commands:

     ESC =     Switch to application mode
     ESC >     Switch to normal mode

Thus, if you can get to a UNIX shell prompt, you can return to normal mode
by typing this:

    echo '^V^[>'

(where "^V" is what you see when you press control-V, and "^[" is what you
see when you press ESC).
