I normally use rxvt running on pmax and displaying on an X terminal, and
I have no problems. Backpace sends ^H and arrows send ^[[A through ^[[D
as they should.

Some questions that may help isolate your problem:
- Do you mean rxvt running on the pmax and displaying on another display,
  or running on another machine and displaying on the pmax display?
- Are you using the rxvt package or one you built yourself? If you build your
  own, try setting FORCE_BACKSPACE in feature.h. If you use the package one,
  check that your stty erase key is ^H.
- Does the X server send the right event when you press the backspace key?
  (If you run xev and press backspace, do you get 'keysym 0xff08, BackSpace',
  or something else?)
