looking at that bug report, i'm guessing that setting length to 0 might
trigger a bug - we've seen that before with other vendors and foundry
nor hp tend to be very resilient.  so, this should probably only send
that cmd if 'no page' fails.

however, i'd first ask from whom hp OEM'd that switch.  it might be that
it would be better served as a different vendor.  if it is an OEM, does
anyone know who made it?
