3270 models

Description
The x3270 family can emulate any of the following IBM 3270 models: Note that models 3, 4 and 5 also implicitly emulate a model 2 as well. When the host sends an Erase Write command, it puts the terminal into model 2. When it sends an Erase Write Alternate command, it puts the terminal into its native mode (2, 3, 4 or 5).
