How to enable TN3270E sessions on OS/390

The IBM OS/390 version 2.8 is capable of supporting TN3270E sessions communicating directly. The following describes the required mainframe definitions for a PrintServer. It is assumed that the TN3270E service is already active on the mainframe.

Mainframe TCPIP profile definitions:


PRTGROUP PRTGRP1                                 

     LU08

     TCPPRT01 TCPPRT02 TCPPRT03 TCPPRT04 TCPPRT05

     TCPPRT06 TCPPRT07 TCPPRT08 TCPPRT09 TCPPRT10

     TCPPRT11 TCPPRT12 TCPPRT13 TCPPRT14 TCPPRT15

ENDPRTGROUP                                      



IPGROUP IPGRP1 255.255.0.0:128.0.0.0 ENDIPGROUP      

LUMAP LUGRP1 IPGRP1 SPECIFIC PRTGRP1                 

PRTMAP PRTGRP1 IPGRP1
