         The following are a summary of Super Serial Card Commands which are
         useful on the Apple IIgs.  The table is abbreviated.  Commands to a
         MODEM port should be preceeded by a Control A (CHR$(1) in Basic.
         Those to a PRINTER port should be preceeded by Control I (CHR$(9) in
         Basic).
