A furthur clarification: GETLN on the IIc, in addition to the cursor
movement keys accepts the following commands:
ESC 8 activates enhanced firmware if not already activated, and sets screen to
      80 columns, preserving the information on the screen.  (if going from
      40 to 80 the right 40 columns will be blank.)
ESC 4 activates the enhanced firmware if not already activated, and sets the
      screen to 40 columns.  The information in the rightmost 40 columns is
      lost if switching from 80 columns.
ESC ctrl-Q switches (back) to old firmware, rightmost 40 columns are lost,
           if switching back from 80 columns

These commands work only if input is being gotten through the routine GETLN.

The above commands as part of their effect, switch in the old or new
character sets.  The values in pages 4-7 are not changed, but some of the
interpretations are (lower case inverse goes to flashing punctuation marks,
or something like that.

These commands presumably work the same on the IIc+ and GS.
