It sounds like lynx isn't correctly resetting the tty options when it
exits.  How many things it isn't resetting isn't obvious from what you
say, but at a minimum it has turned off echo.  It may have changed other
settings.

Try typing

  stty sane

...and hit return, and see if that fixes it.  If not, type:

 ^Jstty sane^J

Where ^J means hold the control-key and hit the J key.  You will probably
see some kind of response after the first ^J, but go ahead and type the
rest of the command followed by the second ^J.


In any case, this seems like a lynx bug.  You might go see if anyone has
reported something similar, and if not, file a new bug report.  (See the
``Report or query a bug'' link from http://www.NetBSD.org/ for doing
this.)


There are a lot of terminal settings available via stty (and the
corresponding programming interface that lynx, etc. use).  But, ``stty
sane'' should restore things pretty much to how they are after a login.
(This seems to be an exact correspondance, but the man-page is a little
vague...)  For more information about the stty command, read ``man stty''.
