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.
