SUMMARY
The TN3270E Server sets the DATA-TYPE Field with a value of 0x08 to indicate a PRINT-EOJ.



MORE INFORMATION
RFC 1647 contains the following text on the DATA_TYPE field:   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.
