Actually, under DOS 3.3, it is DOS that gets disconnected; and under
ProDOS, it is BASIC.SYSTEM that gets disconnected.  Under DOS 3.3, you can
reconnect things with a CALL 1002; I think that under ProDOS you can just
hit <RESET>...or the CALL 1002 should also work under ProDOS, unless Apple
violated their own rules and moved that vector around.  (It wouldn't
suprise me...).

Anyway, while Randy is absolutely correct about using the BASIC PR# and
IN# commands being bad form, the program should still work properly.  It
will just leave you in a machine state where ProDOS might not work
properly.  For testing a printer, it should work just fine.
