vt100's (and xterm, etc) send two types of escape sequence for the cursor keys. 
Only one can be represented in terminfo/termcap at at time.  If the terminal is
not initialized to the proper mode, you'll see the final character of these
sequences as A,B,C,D.  If you're using xterm, you can see which mode the cursor
keys are in using the control/middle/mouse button, (on the window I'm running,
that's a checkmark by the entry "Enable Application Cursor Keys" - your menu
may be worded differently of course).

Most systems initialize the cursor to application mode.  HPUX's native terminfo
entry for xterm does not.  ncurses (following Solaris and the original X
consortium entries) does.  At the moment I'm not sure how to concisely describe
the scenario that would produce the effect you're describing, but I think it's
related to this information.
