<t>This document describes the existing implementation of transferring 3270 display terminal data using currently available telnet capabilities.  The name traditionally associated with this
 implementation is TN3270.</t>
<t>Information is provided to aid in the implementation of TN3270 servers as well as client terminal emulators.</t>
<t>The following areas pertaining to TN3270 implementations are covered in this document:</t>
<t>1. the telnet options negotiated to transition from a NVT ASCII state to a TN3270 state ready to process incoming 3270 data
         stream commands</t>
<t>2. the method for sending and receiving 3270 data</t>
<t>3. the method of handling some special keys known as SYSREQ and ATTN using current available telnet commands</t>
<t>4. the events that will transition a TN3270 session back to an NVT session</t></abstract></front>
