         --------------   ----   ---------------------------------
         3270-DATA        0x00   The data portion of the message
                                 contains only the 3270 data stream.

         SCS-DATA         0x01   The data portion of the message
                                 contains SNA Character Stream data.

                                 and the RESPONSE-FLAG field indicates
                                 whether this is a positive or negative
                                 response (see below).

         BIND-IMAGE       0x03   The data portion of the message is
                                 the SNA bind image from the session
