If the state vars are only used by the enhanced mode then maybe you 
could
sometimes initialise the terminal twice?  That is, first always 
initialise
the enhanced routine (to do the font stuff etc), then as if that had not
been done (but only if noenhanced was set initially) initialise the 
plain
text routine?  Would that leave plain-text in effect exactly as it works
now, but mean that temporary switches into enhanced would work?
