TN3270 Sessions

port could be VT100, VT220-8, ANSI, or a another type defined by the network manager. The list of Enabled Characteristics includes TN3270 EOR, TN3270 ErrorLock, and TN3270 XtdAttrs.

Note: If the TN3270 characteristic is not enabled, you can still establish a session with an IBM host, but your keyboard will not function properly and the screen will be incorrectly formatted.

Using the SHOW PORT KEYMAP Command

The SHOW PORT KEYMAP command, described in Chapter 3, displays the translation table of 3270 keyboard functions and the corresponding keys for those functions on your terminal. The table also includes the hexadecimal value for those keys, although you do not need these values for regular keyboard use. Tables 4-1, 4-2, and 4-3, at the end of this chapter also show 3270 keyboard functions and the corresponding keys on terminal types that are included in the software.

Establishing a TN3270 Session with an IBM Host

Use the CONNECT or TELNET CONNECT commands to establish a session with an IBM host through a Telnet server. You can use a domain name or an Internet address as the destination name in the command. In the following example, a user enters the CONNECT command to establish a session with the IBM host FNC.BOSTON.COM. (Notice that the IBM host name is in Telnet domain name format). Figure 4-2 represents the type of screen that can appear:
