TN3270 style files
The TN3270 program enables you to customize
TN3270 emulation parameters such as color mappings,
HP-UX terminal keys used to represent host 3270 keys,
and HLLAPI session IDs for TN3270 sessions. The
details of this customization are stored in a style file
that is loaded when the TN3270 program is started.
You can set up a standard style for all your TN3270
users, or you can allow users to customize these
settings individually and create their own style files.
