You should never see "the page scroll off the screen" due to any statusline
messages.  That indicates to me that there is something wrong with your
setup - like either lynx or the display library (ncurses? slang?) not
being fully aware of the size you have set with stty, or using an
inappropriate terminfo (or termcap) description.  Something in front of
the telnet client must be providing a terminal emulator - I assume in your
setup it's the "handheld device" that does that - and most likely the
emulation is not correct, incomplete, or doesn't match the capability
description that lynx uses (i.e., $TERM variable).  

Please
 - subscribe to the lynx-dev list for further discussion,
 - describe exactly what you mean with "scroll off the screen" and
   when that happens,
 - give more information on lynx version, OS, how compiled (curses/slang?
   terminfo/termcap?), the $TERM in use.

That stuff is hardwirded, as others have pointed out, in
src/DefaultStyle.c.  The first step should be to change the values there.
There may be hardwired values in some other places, esp. HTML.c, that may
then also need tweaking for consistency; I am not aware of anyone having
tested in recent times how well changing src/DefaultStyle.c works in
practice.  So if you do that, please share your experience.
