It depends on the type of terminal you're using.  Some terminals support an
"alternate keypad" mode, which causes keys on the keypad to send escape
sequences instead of the normal characters.  There's generally control
sequences that can be sent to the terminal to turn this mode on and off; it
may also be settable with the terminal's SET-UP mechanism, if it has one.

In the termcap file, the sequences that turn keypad mode on and off are
notated with "ks=" and "ke=", respectively.
