Configuring and Managing 3270 Terminal Emulation (TN3270) 18-5
Configuring Basic 3270 Terminal Emulation
Terminal Setup Parameters
The following table provides information on terminal setup for the various DIGITAL
terminal models:
Indicating the 3270 Model Number
To enable 3270 emulation on a port, you must specify the 3270 model number as
follows:
Local> CHANGE PORT 2 TN3270 MODEL 2
This command enables port 2 to emulate an IBM 3278 Model 2 display station.
When the access server establishes a session to an IBM host, the host negotiates for an
IBM 3278 display station. If the IBM host does not negotiate for an IBM 3278, then
the access server defaults to a standard Telnet connection.
To disable 3270 emulation on port 2, enter the following:
Local> CHANGE PORT TN3270 NONE
By default, 3270 emulation is disabled on all ports.
Specifying the Type of ASCII Terminal Used for Emulation
After you indicate the 3270 model number, you need to specify the type of ASCII
terminal. For example, to indicate that a VT220 is attached to port 2, you enter:
Local> CHANGE PORT 2 TN3270 TERMINAL VT220
To display the list of terminal types and their associated keyboard maps, enter the
SHOW TN3270 TERMINAL command. The default terminal device is VT100.
