HPE-UX TN3270 Client allows interactive communications between an HPE 9000 server or workstation and an IBM System/370-compatible mainframe, or other system acting as a TN3270 server, using 3270 data streams in a TCP/IP environment. HPE terminals and monitors on the HPE 9000 running TN3270 emulate the functions of IBM 3278/3279 terminals for access to 3270 applications such as TSO, CMS, and CICSr. TN3270 provides additional functions beyond emulation to include such features as file transfer, HLLAPI application programming interface, Motif graphical user interface, a character-oriented windows user interface, and multiple session/connection support.
TN3270 communication can be implemented in either standalone or client/server configurations. The standalone configuration provides direct access to TCP/IP-based mainframes or peer systems for HPE-UX computers, which have their own TCP/IP-based network interface (802.3, Token Ring, FDDI, or X.25). The client/server configuration permits access to an SNA-based host system from multiple HPE-UX computers on an 802.3, Token Ring LAN, or FDDI. These HPE computers generally use a single HPE 9000 system with HPE-UX SNAplusLink (which includes TN Server function) as a gateway to access the IBM system.
