In the list of commands that the SUN terminal emulator groks is a note
that the sequence <ESC[s> will reset the terminal to a sort of virgin
state.  Especially useful is that it undoes the set-scrolling-area
limit of 24 lines that your vt-100 tset did.  Stick it in the
initialization or reset string for the Sun termcap.  Or you could put an
explicit set to 34 lines in the Sun termcap with <ESC[1;34r>.
