IBM 3270 Emulation
This chapter describes features of the IBM 3270 terminal emulation.
Introduction
The IBM 3270 emulator provides emulation of all four models of the IBM 3278
alphanumeric terminal and also supports the IBM 3287-1 printer. The terminal
emulation supports Extended Attribute mode which allows different representation of
highlighted fields and permits host definition of text colours. (Note that you can
modify colours using the Attribute Settings dialog box but they cannot be saved as
colours are mapped differently in this mode.) The emulation also includes typeahead
capability so that you can continue to enter data without waiting for a prompt from
the host. All communication to the IBM mainframe is achieved over the TCP/IP
Telnet interface using the inbuilt telnet interface provided with TeemTalk.
Running The Emulation
1. Display the Emulation Settings dialog box, set the Alpha Emulation option to
IBM 3270, then click Ok. The TeemTalk window will now be in Network Virtual
Terminal mode, as indicated by the
?
symbol in the status line along the bottom of
the window.
2. The Model option in the IBM 3270 Settings dialog box specifies what is reported
back to the host in response to a terminal identification request. (Note that not all
features of the specified terminal may be supported.) It also determines the size of
the display and whether or not extended attributes are supported. One of four
display sizes can be selected:
Model 2
24 rows by 80 columns
Model 3
32 rows by 80 columns
Model 4
43 rows by 80 columns
Model 5
27 rows by 132 columns
