A method, system, and computer program product for communicating structured document content between legacy 3270 logical units. A 3270 data stream is sent between a primary logical unit (LU) and a secondary LU over a network using 3270 data stream architecture, with structured document content (such as content encoded in the Extensible Markup Language, or "XML") embedded therein. The sending of 3270 data stream communications and the sending of 3270 data stream structured fields are repeated in an arbitrary sequence, to thereby asynchronously send 3270 data streams and structured document content between the primary LU and the secondary LU. Thus, structured documents may be sent using the LU2 protocol in a manner that need not interfere with legacy communications between a 3270 application and an end user.
