   8.1 The TN3270E Message Header

      As stated earlier, each data message in TN3270E must be prefixed
      by a header, which consists of five bytes and is formatted as
      follows:

      -----------------------------------------------------------
      | DATA-TYPE | REQUEST-FLAG | RESPONSE-FLAG |  SEQ-NUMBER  |
      -----------------------------------------------------------
         1 byte        1 byte         1 byte         2 bytes

   8.1.1 DATA-TYPE Field

      The DATA-TYPE field indicates how the data portion of the message is
      to be interpreted by the receiver.  Possible values for the DATA-TYPE
      field are:

         Data-type Name   Code                Meaning
         --------------   ----   ---------------------------------
         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.

         RESPONSE         0x02   The data portion of the message
                                 constitutes device-status information
                                 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
                                 established between the server and the
                                 host application.

         UNBIND           0x04   The data portion of the message is
                                 an Unbind reason code.

         NVT-DATA         0x05   The data portion of the message is to
                                 be interpreted as NVT data.

         REQUEST          0x06   There is no data portion present in
                                 the message.  Only the REQUEST-FLAG
                                 field has any meaning.

         SSCP-LU-DATA     0x07   The data portion of the message is
                                 data from the SSCP-LU session.
