  About TN3270 Service Setup


Welcome to TN3270 Service Setup

TN3270 Service combines client/server architecture with the power and productivity of the Windows NT system. By using TN3270 Service you can provide access to your host mainframe environment for TN3270 clients using 3270 terminal emulation services. TN3270 Service also includes support for TN3270E clients, including printing.

TN3270 Service is implemented as a Windows NT Service in the SNA Server environment. SNA Server and TN3270 Service communicate via SNA Server-based Logical Unit Application programming interface (LUA). TN3270 Service communicates with TN3270 clients over a TCP/IP connection using the TN3270 protocol.

TN3270 Service is a client to the SNA Server and a server to TN3270 clients.
